  • Gravitational Interactions of Two Small Evaporating Drops

    • Free pre-print version: Loading...

      Abstract: Abstract The effect of evaporation on relative trajectories of two spherical drops sedimenting due to gravity in air is investigated. Theoretical analysis and numerical simulation of the interactions are used to obtain results. Several assumptions are made in the model. The drops remain small enough that the Reynolds number, which is linear in the density of the surrounding fluid, is negligible. However, the Stokes number, which is proportional to droplet mass and is a measure of drop inertia, can be much larger than one. Another restriction is that evaporation is dominated by diffusion and that convection of mass is insignificant. In analyzing evaporation when two drops are present, it is noted that the loss of mass is not the same at each point on a droplet surface. That is, evaporation is non-uniform in a spatial sense. In order to maintain the required spherical drop shape, three approaches, involving the isolated droplet and bispherical coordinate solutions, were taken to determine the mass flux due to evaporation and subsequently the drop position at each time step. For a pair of water drops with radii between 2 and 30 \(\upmu\) m, the following conclusions were obtained. In all three methods, evaporation leads to weaker inertial effects and stronger hydrodynamic effects. Most importantly, in comparing critical horizontal offsets, when both attractive molecular forces and Maxwell slip are considered, all three approaches to evaporation lead to similar results, making the choice of method nearly inconsequential.

  • A Review of Atmospheric Aerosol Impacts on Regional Extreme Weather and
           Climate Events

    • Free pre-print version: Loading...

      Abstract: Abstract Atmospheric aerosols are essential constituents of the atmosphere and also interact with radiation and clouds. Substantial progress has been made since the industrial era majorly for observing, understanding, and modeling processes and these research efforts have helped to identify how aerosol optical properties have contributed to radiative forcing that influence regional and global climate. Research findings have also helped to quantify the imbalance in the Earth's radiation budget caused by anthropogenic aerosols as well as various other ways aerosol has contributed to global warming both at the regional and global scale. Several aerosol inventories have been developed to quantify different aerosol species including the emission, life span, sizes, and transportation from one region to another and as well as the influence of the surrounding environment on aerosol characteristics. In recent times new metrics have been developed for adequate measurements to quantifying aerosol radiation and cloud interaction including Aerosol Instantaneous Radiative Forcing (IRF) which is the changes that occur in the Earth's energy balance due to the direct interaction of aerosols with incoming solar or outgoing infrared radiation and can lead to warming or cooling of the atmosphere, depending on the aerosol type (e.g., sulfate aerosols cause cooling). Rapid adjustment also referred to as a swift in atmospheric response to changes in radiative forcing, including adjustments in temperature, humidity, and cloud cover. It occurs almost immediately, influencing local and regional climate conditions alongside aerosol or greenhouse gas emissions. On the other hand, after taking into consideration quick corrections and feedbacks, the Effective Radiative Forcing (ERF) represents the net change in Earth's energy balance. By recording both short- and long-term feedbacks, it offers a more thorough knowledge of the total impact of aerosols or other agents on climate. These metrics are employed to precisely estimate net radiation perturbation, even though the actual measurement values of these three recently developed metrics continue to fluctuate inexplicably throughout the regions. This review provides information on various aspects of aerosol properties especially those that are related to radiation, cloud interaction, and extreme events. The new paradigm shifts to a modeling approach, theoretical considerations, and finetuned observational methodology are essential tools to be considered. Scattering and absorption of aerosol show different mechanisms involved when aerosols interact with short and long-wave radiation but aerosol absorption ability might not only be limited to certain aerosol species as entailed in research consensus and these might be one of the major constraints of surface radiative fluxes from aerosol-radiation interactions. The influence of anthropogenic aerosols on cloud liquid water content and cloud fraction was also considered and it has been discovered that these complex processes are less clear, and the influence on mixed-phase and ice clouds remains to be well understood. Observed changes in surface temperature increase due to radiation perturbation and the radiative fluxes both at the Top of the Atmosphere and at the surface are the major driving force for global warming and also impacts weather and climate extreme events. It is also very important to measure with high sense of accuracy the changes in the surface temperature. The degree of aerosol-induced warming on global circulation as the major carrier of moisture for precipitation processes is yet to be fully explored. The extreme events associated with flood events and as well as drought associated with extreme temperature and heat waves are key areas for current and future research. In summary, if we must consider importance and the usage of the three invented metrics for accurate and scientific quantification over the traditional Direct and Indirect aerosol radiative forcing then there is a need for proper understanding and a better research approach to allay the fear of uncertainty in this regard. The application of new technological tools and as well as new parametrization schemes development that express micro aerosol-climate interaction and processes that are smaller and cannot be resolved or captured explicitly on regional and global scales are important factors to be considered.

  • Validation of AERMOD Prediction Accuracy for Particulate Matters (PM10,
           PM2.5) for a Large Coal Mine Complex: A Multisource Perspective

    • Free pre-print version: Loading...

      Abstract: Abstract Particulate matter (PM) emission from coal mining activities is inevitable and a significant concern worldwide. American Meteorological Society/Environmental Protection Agency Regulatory Model (AERMOD) is one of the most widely used dispersion models for predicting air PM dispersion in coal mines. However, validation of AERMOD-predicted PM concentration in a large mine complex has not been reported. So, in this study, AERMOD predicted PM concentration was validated against the PM concentrations measured by nine continuous ambient air quality monitoring stations (CAAQMS) stationed in the Singrauli coal mining complex. The complex contains nine coal mines across 438 square kilometers, with around 129 pollution sources chiefly from the area, pit, and line categories. PM10 and PM2.5 concentrations peak during summer (204.58 µg/m3) and winter (67.67 µg/m3), respectively. The AERMOD model predicts peak dispersion of PM10 (500–1200 µg/m3) and PM2.5 (100–800 µg/m3) during the winter season. The AERMOD model reveals that the region’s wind movement caused by land and lake breezes was the predominant driver of PM surface dispersion. In the winter season, atmospheric inversion increases ground-level PM concentrations in the region. The AERMOD cannot represent the vertical dispersion of PMs in the summer, resulting in an underestimation of PM concentration. The statistical validation shows that AERMOD underestimates PM10 and PM2.5 concentrations across all seasons and years. The AERMOD model’s prediction accuracy for PM10 (R2 = 0.38) and PM2.5 (R2 = 0.56) is also low. Finally, it can be concluded that AERMOD-predicted PM concentrations are not accurate for large mining complexes but more suitable for individual mines.

  • Impact of Ultra-Low Emission Technology of Thermal Power Plants on Air
           Quality in China

    • Free pre-print version: Loading...

      Abstract: Abstract China is confronted with a severe air pollution challenge, wherein thermal power generation plays a significant role. In recent years, substantial efforts have been made in ultra-low emission retrofitting of coal-fired power plants, however, quantitative study regarding its subsequent impact on air quality is limited. In this study, we estimated the emission reduction of thermal power plants from the perspective of online monitoring system during 2014 ∼ 2016, and investigated the accompanying impacts on air quality in typical regions of China by using a regional chemical model WRF-Chem. The results indicate that the ultra-low emission retrofitting of thermal power plants, which was initiated in 2014, has achieved significant progress, with nearly 80% of planned tasks completed by 2016. As a result, emissions of SO2, NOx and PM2.5 from thermal power plants notably decreased by 67.5%∼72.8% nationwide between 2014 and 2016. WRF-Chem simulations demonstrate that the ultra-low emission retrofitting effectively reduces air pollutant concentrations. Specifically, the monthly mean concentrations of SO2, NO2 and PM2.5 in typical regions have decreased by 0.6 ∼ 1.7, 2.2 ∼ 3.7 and 2.6 ∼ 5.0 µg m− 3, respectively, representing an improvement of 3.1%∼10.4%, particularly notable in winter. Regional variations in installed thermal power capacity and completion of the ultra-low emission retrofitting have led to differential improvements in air quality, with the Yangtze River Delta region exhibiting the most significant reduction in air pollution concentrations, surpassing the Beijing-Tianjin-Hebei and Pearl River Delta regions by up to 2.2 µg m− 3. This study serves as a valuable reference for the ultra-low emission retrofitting of thermal power industry and provides essential data support for future air quality management strategies.

  • Health and Economic Benefits of Lowering Particulate Matter (PM) Levels:
           Scenarios for a Southern Brazilian Metropolis

    • Free pre-print version: Loading...

      Abstract: Abstract Several studies have reported reductions in atmospheric particulate matter (PM2.5 and PM10) during the social isolation period of the COVID-19 pandemic. We evaluated the monetary and health benefits of PM emission reductions in the short and long term in the city of Florianópolis, Brazil (half a million inhabitants). We collected information on PM10 and PM2.5 concentrations from 2018 to 2020, and population and health-related data (mortality and hospitalizations due to heart and respiratory problems) from 2018 to 2019. The Health Impact Assessment (HIA) tool was applied to the APHEKOM model and two different scenarios were evaluated. In the first scenario, PM levels remained throughout the year at the same average level as the most restrictive period of human mobility to contain Sars-CoV-2 infections. In the second, PM levels remained at WHO recommended levels throughout the year. In the first scenario, PM2.5 reduction would prevent 35 annual deaths from non-external causes and 21 annual deaths from cardiovascular diseases. In addition, PM10 reduction would prevent 28.9 respiratory hospitalizations and 12 cardiovascular hospitalizations, saving the public purse more than US$ 313,000 per year. In the second, based on WHO recommended levels, a reduction in PM2.5 would prevent 47.7 annual deaths from non-external causes and 28.3 annual deaths from cardiovascular disease. Reducing PM10 concentrations would also prevent 53.2 respiratory hospitalizations and 22.1 cardiac hospitalizations, resulting in savings of more than US$ 577,000/year. Therefore, a sustainable PM reduction that does not require the cessation of human activities could improve the quality of population health and reduce hospitalization costs.

  • Chemical Characteristics and Public Health Risk Assessment of PM2.5-Bound
           Elements in Sheohar, India

    • Free pre-print version: Loading...

      Abstract: Abstract In order to measure the seasonal variations, source identification, and human health risk of elements in PM2.5 were collected from January 2021 to December 2021 at an urban site in Sheohar, India. Element (Na, Mg, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, and Pb) concentrations were estimated using an inductively coupled plasma optical emission spectrometer (ICP-OES). The enrichment factors (EFs) and principal component analysis (PCA) were used to identify the sources of these elements, and the United States Environmental Protection Agency (US EPA) models were used to evaluate the carcinogenic and non-carcinogenic risks to both children and adults. The results showed that the annual mean concentration of PM2.5 was 104.22 μg m−3 which exceeded the National Ambient Air Quality Standards (NAAQS, 40 μg m−3) and the World Health Organisation (WHO, 10 μg m−3) limits. The seasonal variation of PM2.5 was characterised by high concentrations in winter, followed by post-monsoon, summer, and monsoon. The average annual concentrations of As, Cd, Ni, and Cr were 17.25 ng m−3, 32.68 ng m−3, 158.16 ng m−3, and 177.41 ng m−3, respectively, which were above the WHO limits. The concentrations of Ca and Fe were highest in the summer season. The concentrations of Mg and Na were highest in the monsoon season. The other element concentrations were highest in the winter season. Enrichment factor analysis showed that Zn, As, Pb, and Cd were predominantly from anthropogenic sources. In addition, source apportionment by PCA identified six components for the studied elements. The total carcinogenic and non-carcinogenic risks of elements exceeded the safe level of exposure for both children and adults, which indicate further research on sources of air pollution and measures for controlling pollutants in Sheohar, India.

  • Numerical Research on Aerosol Transport and Deposition Inside a Heat
           Exchanger Tube Based on Lagrange Methodology

    • Free pre-print version: Loading...

      Abstract: Abstract The passive containment cooling system adopted in advanced light water reactors can enhance the natural removal of suspended aerosols inside containment during accidents. The primary removal mechanism is the diffusiophoresis in steam environments with the presence of non-condensable gas. The lumped-parameter methodology is widely used to calculate the natural removal of aerosol in the nuclear industry, which cannot obtain the mechanistic analysis of aerosol behavior. A numerical simulation methodology based on the Euler–Lagrange system was developed in this paper for the mechanistic analysis. COPAIN experiments and a hypothetical case validated the steam wall condensation model and aerosol diffusiophoresis model in this methodology. Then the experiments on aerosol transport and deposition inside a heat transfer tube were simulated using the validated numerical methodology. The simulation results agree well with the experiments. Numerical analysis indicates that the aerosol deposition rate decreases with increasing particle size with the combination effect of Stefan flow, thermophoretic, and diffusiophoretic forces. Stefan flow plays a dominant role; In the steam–air environment, diffusiophoretic force slightly weakens the aerosol wall deposition. The numerical simulation methodology developed in this work can be used to mechanistically analyze the behavior of aerosol transport and deposition inside containment during accidents.

  • Numerical Investigations of Exhaling Respiratory Aerosol from Inside of
           the Human Respiratory Tract

    • Free pre-print version: Loading...

      Abstract: Abstract The characteristics of exhaled aerosol outside the human respiratory airway are of significant importance in understanding virus transmission, yet they remain poorly understood. In order to effectively prevent and control the spread of respiratory infectious diseases, this study numerically investigates the exhaling characteristics of respiratory aerosol exhaled from the bronchus or larynx of a human upper airway model. This is achieved using the Euler–Lagrange method and considering various aerosol diameters (dp = 0.1, 0.3, 0.5, and 1–20 μm) as well as five expiratory flow intensities (Q = 15, 30, 60, 90, and 120 L/min). The important findings of this study are as follows: (1) Expiratory airflow exhibits complex flow phenomena, including jet-flow, flow separations, and vortex structures, with their characteristics being influenced by the expiratory flow intensities. (2) The exhaling characteristics of aerosol vary depending on the combined effects of expiratory flow intensities, aerosol diameters, and initial exhaled locations from either the bronchus or larynx. (3) A critical diameter (dc) is identified to represent the size at which aerosol can effectively exit the respiratory airway and potentially pose a transmission risk. This critical diameter is identical for aerosol exhaled from both the bronchus and larynx under the same expiratory flow intensity, but it decreases as the expiratory flow intensity increases. In conclusion, expiratory flow intensity is the most critical factor in determining whether aerosol droplets can be expelled from the respiratory airway, as well as influencing the critical diameter (dc) for aerosol droplets initially located in/after the larynx.

  • Influence of the Turbulence Effect on the Rainfall Scavenging Coefficient

    • Free pre-print version: Loading...

      Abstract: Abstract Rainfall removal of aerosol particles is an important atmospheric aerosol self-scavenging process. Studying the scavenging mechanism of rainfall on aerosol particles and developing a suitable theoretical model are of great significance for preventing and controlling aerosol pollution and improving the accuracy of air quality forecasting. In this paper, the influence of the turbulence effect on aerosol capture by raindrops is investigated using numerical simulation, and the contribution of the turbulence effect to the capture of aerosol particles by raindrops, Et, is given via the introduction of dimensionless parameters. The scavenging coefficients of the accumulated model particles calculated by simultaneously considering seven mechanisms, namely, Brownian diffusion, interception, inertial impaction, thermophoretic action, diffusiophoretic action, electrostatic action, and the turbulence effect, were found to be 2–10 times higher than those calculated using the currently commonly used Slinn formula (which considers only Brownian diffusion, interception, and inertial impaction). A rainfall scavenging of polydisperse aerosol prediction model was established by taking the actual rainfall events in Guangzhou City, China, as an example and considering seven mechanisms simultaneously, and the characteristics of small particulate matter (PM2.5) changes over time simulated using the model matched well with the actual measurements.

           Episodes in Xi’an, Northwestern China: Estimation of the Potential of
           Carbon Emission Reduction by Rural Household Energy Substitution

    • Free pre-print version: Loading...

      Abstract: Abstract The carbonaceous aerosol source apportionment is crucial for targeted prevention and control of PM2.5 in China. The 24 h integrated PM2.5 samples were collected from Xi’an, China during pollution events in 2015 in summer (biomass open burning period) and winter (haze period). Source apportionment of carbonaceous aerosols in PM2.5 was conducted using radiocarbon (14C) and levoglucosan (a biomass combustion tracer). Results showed that in the study period of biomass open burning in the wheat harvest season (early June) in Xi’an, fossil and non-fossil sources contributed approximately 47% and 53% to total carbon (TC), respectively. In the haze pollution period, non-fossil sources dominated water-insoluble organic carbon (WISOC) at around 53%, and fossil sources accounted for about 71% of elemental carbon (EC), with the rest from biomass combustion. The usage of coal and biomass for heating in the study period in winter increased the contribution of fossil fuel combustion to carbonaceous aerosols, particularly EC. In order to reduce PM2.5 and carbon emission in Xi’an, controlling biomass fuels burning in summer and solid fuels use in winter are essential. Biomass fuel is a renewable negative carbon fuel, contributing significantly to greenhouse gas emission reduction. After estimation, biomass fuel usage by rural residents in Xi’an in 2015 reduced by 545,000 t of CO2 equivalent emission, with a carbon benefit of 38.1 million yuan. Replacing scattered coal with biomass fuel could further reduce 75,500 t of CO2 equivalent emission, generating a carbon gain of 5.29 million yuan.

  • Estimating the Key Factors Contributing to Vehicular Exhaust Emission in
           Ghana

    • Free pre-print version: Loading...

      Abstract: Abstract The study examined the factors that contribute significantly to automobile exhaust pollution in the major city of Ghana, Accra. Using an SV-5Q automobile exhaust-gas analyzer, the concentrations of carbon dioxide (CO2), hydrocarbon (HC), carbon monoxide (CO), and nitrogen oxides (NOx) were measured on 1002 light-duty gasoline automobiles taking into consideration age, maintenance, and emission technology (catalytic converters). To achieve the aim of the study, the emissions data gathered were analyzed against the vehicle parameters (Age of the vehicle, Frequency of maintenance, and Emission technology). The significant parameters explained variance of 42%, 22%, 32%, and 7% in CO, CO2, HC, and NOx, respectively. The results showed that the age of a vehicle is a significant positive predictor of CO, CO2, and HC emission but has no significant effect on NOx. The result further shows that the frequency of maintenance negatively predicted HC emissions with no significant effect on CO, CO2, and NOx. The results also demonstrated that emission technology was consistently negatively related to CO, CO2, HC, and NOx. Finally, the result established that an increase in vehicle age increases the emission level, while regular vehicle maintenance, two-way and three-way catalytic converters fitted on vehicle exhaust system decrease the exhaust emission level.

  • Heterogeneous Nucleation of Vapor on Insoluble Particles Predicted by an
           Improved Classical Nucleation Theory

    • Free pre-print version: Loading...

      Abstract: Abstract The classical nucleation theory (CNT) plays an important role in the investigation of vapor heterogeneous nucleation on solid surfaces. However, the CNT relies on the macroscopic surface tension to describe the formation of a nano-sized embryo, which inevitably causes the model inaccuracy. In this study, an improved CNT is developed by integrating the microscopic surface tension as a function of the embryo size obtained using the molecular dynamics (MD) simulation to enhance the model accuracy. The important heterogeneous nucleation behaviors, including the Gibbs free energy of embryo formation, critical saturation ratio, and nucleation probability, are numerically investigated by the improved CNT. Compared with the CNT with the macroscopic surface tension, the improved CNT using the microscopic surface tension predicts lower Gibbs free energy of embryo formation, lower critical saturation ratio, and higher nucleation probability, particularly when the contact angle of the particle is large. The improved CNT proposed in this study is validated by comparing the numerically predicted critical saturation ratios for the heterogeneous nucleation of water vapor on planar surfaces and on nano- and micron-sized insoluble particles with the experimentally measured data published in literature.

  • Footprints of COVID-19 on PM2.5/PM10 Ratio in a Brazilian Tropical
           Metropolis

    • Free pre-print version: Loading...

      Abstract: Abstract PM2.5/PM10 ratio is a metric that is used both to determine the main origin of particulate matter and to evaluate the concentration of one component in the absence of monitoring for the other. However, further research is required to fully understand the relationship between this ratio, its components, and meteorological conditions in various scenarios. This study analyzed the effect of COVID-19 restrictions on the PM2.5/PM10 ratio in Recife, Brazil. The data showed that the PM2.5/PM10 ratio significantly decreased in 2020 due to the reduction in urban mobility and human activities. The strictest restrictions were maintained in the state until August and as soon as the first major loosening took place, the ratio began to approach typical pollution levels. The average daily PM2.5/PM10 ratios for 2020, 2021 and 2022 were 0.52 ± 0.08, 0.58 ± 0.03 and 0.58 ± 0.02, respectively, lower than those found in other metropolitan areas. During the phases of greater restrictions, the PM2.5/PM10 ratio had an average value of 0.48 ± 0.08 and as restrictions were lifted, it became 0.56 ± 0.03. The results showed that the reductions observed in 2020 were directly related to the decrease in anthropogenic emissions of PM2.5. A machine learning approach was used to estimate the expected PM2.5/PM10 ratio, corrected for the meteorological conditions and it was found that the observed ratios were lower than expected even in this scenario. Furthermore, only temperature and wind speed presented significant correlation to the PM2.5/PM10 ratio in both the scenarios with and without restriction of activities. Our study provides valuable insights into the efficacy of restriction measures in the Brazilian tropical and coastal metropolis of Recife and also highlight the intrinsic relation between the ratio and the local meteorological variables.

  • Mineralogical Characteristics and Sources of Coarse Mode Particulate
           Matter in Central Himalayas

    • Free pre-print version: Loading...

      Abstract: Abstract This study investigates the morphological and mineralogical characteristics of coarse mode particulate matter (PM10) over the Central Himalayan region of India (Nainital: 29.39°N, 79.45°E, 1958 m above mean sea level). X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), and Scanning Electron Microscopy-Energy Dispersive X-ray (SEM–EDX) techniques were employed for morphological and mineralogical analysis of PM10 collected from January to December 2019. XRD and FTIR techniques identify crystalline phases, revealing minerals such as illite, kaolinite, montmorillonite, quartz, dolomite, calcite, magnetite, hematite, gypsum, halite, mascagnite, augite, albite, wollastonite, and calcium aluminium silicate hydrate (C-A-S=-H) in PM10 samples. SEM–EDX analysis confirms the presence of major elements i.e., Si, Al, Ca, K, Fe, Mg, S, Na, Ba, Ti, Zn, and Cl in PM10, indicating the diverse mineral formations. Elemental composition variations are observed, with Si, and Al being predominant. The minerals' elemental composition suggests geogenic sources (e.g., dust storms, rock weathering) for quartz, dolomite, albite, augite, etc., containing Al, Si, Na, Ca, Mg, and Fe. Meanwhile, illite, montmorillonite, mascagnite, hematite, calcium aluminium silicate, etc., with elements like Ca, Al, Si, Fe, K, Zn, Ti, Ba, S, and Cl, are linked to anthropogenic sources (e.g., demolition, construction, combustion, industrial and vehicular emissions). These findings contribute to a better understanding of air quality, environmental conditions, and potential health implications in the Central Himalayan region.

  • The Orthogonal Analysis of Selected Influence Factors for Bioaerosol
           Samplers in an Aerosol Generating Chamber

    • Free pre-print version: Loading...

      Abstract: Abstract A high-efficiency bioaerosol sampler is a necessary tool to capture airborne pathogenic microbes, and can effectively ensure the concentration and biological viability of the microbes for further biological and medical analysis. The Andersen sampler and Fuji cyclone were applied in the bacteria and virus under a bioaerosol emission chamber. The four factors selected for this study were temperature, microbial culture concentration, aerosol emission time, and the placing position of biosamplers, and each influencing factor with its varying levels were optimized by orthogonal analysis to evaluate the sampling efficiency of alternative biosamplers under both bacterial and viral environment in a bioaerosol generating chamber. The Andersen impactor had a better collecting effect than Fuji cyclone under four influence factors in bacterial aerosol environment. In the viral aerosol collection, a high air flow rate Fuji cyclone has a better performance for collecting viral aerosol without considering the viability. The two best factors from both Andersen and Fuji were the emission concentration and the angle of 45° sampler placing position under bacteria environment. The two best factors from both Andersen and Fuji were the temperature and the emission time under the virus environment.

  • Numerical Study on the Flow Field Characteristics and Dust Removal
           Efficiency of Tubular Electrofiltration Equipment

    • Free pre-print version: Loading...

      Abstract: Abstract Tube electrofiltration equipment is mainly used to remove fine particles from exhaust gases and separate them from the emission source. In this paper, we study the flow field characteristics and dust removal efficiency of tubular electrofiltration equipment through numerical simulation. The multi-field coupling model of tubular electrofiltration equipment can be used to investigate the internal ion wind (EHD flow) of tubular electrofiltration equipment and its impact on dust removal efficiency. Furthermore, this approach can also be used to evaluate the particle motion trajectory and its impact on dust removal efficiency in tubular electrofiltration equipment under different particle sizes, air flow velocities, and discharge voltages. The results demonstrate that increasing the airflow rate gradually decreases the influence of EHD flow on the airflow field, the removal effect of particles with size < 6 μm by the EHD flow becomes concealed, and the influence on the overall dedusting efficiency becomes negligible. When the particle size dp and discharge voltage U are increased, the charge elevates and the electric field force strengthens, resulting in particles being guided towards the dust collection electrode and increasing the offset, thus improving the dust removal efficiency. When the gas flow rate u is increased, the offset of particles decreases and the dust removal efficiency declines. The optimal operating conditions for the tubular electrofiltration equipment are U = 45 kV, u = 0.5 m/s, and dp ≥ 6 μm.

  • Optimization of the Air Cleaning Properties of Fog

    • Free pre-print version: Loading...

      Abstract: Abstract Fog droplets are very often used as a cleaning agent when air pollution can be dangerous for health conditions and ecosystem. This work presents a new system to optimize the cleaning properties of fog by tuning its microphysical parameters. For this purpose, a newly developed system, which is based on the electromagnetic echo effect (EMEE) sensor, is used to detect the most efficient interaction between fog and impurities, i.e., which fog droplets can be used to most effectively clean a certain type of pollutant from the air. Fog droplet spectra controlled by the nozzle pressure system can be used to effectively remove pollutants from the air. For this purpose, an automated system for aerosol generation can allow an accurate control over the fog microphysical parameters and the use of fluids with specific concentrations of pulverized chemical compounds. Fog droplet size distribution is controlled by the feeding gas pressure at the nozzle and chemical simulants. The experimental results showed that the microphysical parameters (MP) are directly related to the impurity of species used in the cleanup simulation process. The MP parameters of fog are liquid water content (LWC), droplet mean radius (Rm), droplet number concentration (Nd), and both aerosol type and mass concentration. In the lab testing, harmless simulants of CBRN (chemical, biological, radiological and nuclear) species were used. During the tests, fog droplet size distribution is controlled by the air pressure at the nozzle and simulants. It is concluded that an integrated fog generator system (IFGS) with EMEE sensor developed in the current work can be utilized broadly to control fog microphysical parameters, leading to an optimum aerosol/chemical species’ cleaning process.

  • Change Characteristics and Source Apportionment of Ozone Pollution in
           Sanya City in 2019

    • Free pre-print version: Loading...

      Abstract: Abstract Sanya has geographical and climatic characteristics such as low latitude, high temperature, high salt, high humidity, and strong solar radiation all year round, which is conducive to the occurrence of photochemical reactions; therefore, the problem of ozone photochemical pollution in Sanya needs to be solved urgently. This article is based on the hourly data of O3 and NO2 in Sanya City in 2019, various collected meteorological data, and online monitoring of VOCS major species data to analyze the characteristics of ozone pollution changes and source apportionment in Sanya City. The results indicate that the daily variation characteristics of ozone pollution in Sanya City conform to the typical characteristics of ozone photochemical pollution events, and the EKMA curve indicates that Sanya City as a whole belongs to a NOX-sensitive area. The OH consumption rate (LOH) and ozone generation potential (OFP) indicate that the key active components of VOCS are mainly isoprene, ethylene, n-butane, propane, etc. The corresponding main potential sources of emissions include combustion emissions, solvent volatilization, and automotive exhaust emissions. The O3 emission reduction plan is to reduce the ozone concentration from 180 to 158 µg·m−3, corresponding to a 25 and 20% reduction in the concentrations of the two main precursors, NOX and VOCS, respectively. This article provides scientific support for the problem of ozone photochemical pollution in Sanya City.

  • Multi-perspective Investigations of Aerosol’s Non-linear Impact on
           Unmanned Aerial Vehicle for Air Pollution Control Applications Under
           Various Aerosol Working Environments

    • Free pre-print version: Loading...

      Abstract: Abstract The primary focus of this investigation is to create a unique main rotor equipped rotary-wing unmanned aerial vehicle (RWUAV) to detect and mitigate air pollution, which is major concern in modern civilization. This RWUAV was designed after careful consideration and analysis in a variety of maneuvering phases under the fluid particle-based aerosol conditions. This method of spraying the atmosphere using an RWUAV is meant to eradicate fog and other airborne pollutants. The RWUAV takes a mixture of hydrogen peroxide and nitric acid solution, which it then sprays into the air. The aerodynamic parameters are estimated using ANSYS Workbench 17.2 equipped with computational fluid dynamic (CFD) solver, i.e., Fluent and ANSYS Workbench 17.2 with Finite element analysis (FEA) solver has been used to assess the RWUAV imposed with a variety of lightweight materials. The aforementioned multi-computational techniques are used to examine the structural robustness and aerodynamic performances under different airflow circumstances. As the load acting on the proposed RWUAV in aerosol-rich environment will be different than the normal environment, thus the need of this study to determine suitable material which will be structurally stable in both the environments. Thus, from the cumulative results of the structural analyses for both VTOL and forward maneuverings of the RWUAV it can be concluded that for VTOL the materials CFRP-WN-230-wet, CFRP-WN-230-ppg, CFRP-UD-230-wet, CFRP-UD-230-ppg, GFRP-S-UD, and GFRP-E-UD have proven to perform better than other lightweight composites. And from the cumulative results of structural analysis for forward motion the materials CFRP-UD-230GPa-ppg, CFRP-UD-230GP-wet, and GFRP-S-UD have proven to perform better than other lightweight composites. Thus, in conclusion CFRP-UD-230GPa-ppg, CFRP-UD-230GPa-wet, and GFRP-S-UD are better materials for RWUAV for better performance under aerosol heavy environment as these materials have shown promising results for both VTOL and forward motion under both normal environment and aerosol heavy environment. Developing this RWUAV would be helped along by the fact that this RWUAV might be made in a way that is less harmful to the environment.

  • Spatio-Temporal Dynamics of Aerosol Optical Thickness derived Using
           MODIS-MAIAC Algorithm at a High Spatial Resolution Along with the HYSPLIT
           Trajectory Model

    • Free pre-print version: Loading...

      Abstract: Abstract Aerosol is a key component in the climate system. Limited ground monitoring stations impede the acquisition of spatial and temporal aerosol concentration data. However, Remote sensing can provide wider coverage and real-time data, compensating for ground coverage constraints. In the present study, the spatial and temporal variation of Aerosol Optical Thickness (AOT) was analyzed for the Indian cities having significantly different meteorology and geographical conditions like Jaipur and Pune for the years 2020 and 2021 using the Multi-Angle Implementation of the Atmospheric Correction (MAIAC) algorithm. The seasonal mean AOT in winter, pre-monsoon, and post-monsoon are recorded as 0.56, 0.62, and 0.89, respectively, over the entire Jaipur district. However, it was recorded as 0.76, 0.62, and 0.52, respectively, over the entire Pune district. Results of the seasonal analysis indicate that Jaipur and Pune experience high loads of aerosol during post-monsoon and winter, respectively. In this context, the back trajectory, developed through the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model, revealed that Jaipur experiences air masses and emissions from the northern region of India during the post-monsoon. However, Pune encounters air masses from the eastern region of India in winter. The mean Angstrom exponent values at Jaipur and Pune aid in understanding the size and type of aerosol. Jaipur and Pune experience biomass burning aerosol and mixed aerosols to a greater extent, respectively. The performance of MAIAC-derived AOT was assessed using Aerosol Robotic Network (AERONET) sun-photometers derived AOT at Jaipur and Pune with coefficient of determination (R2) values of 0.88 and 0.71 and Root Mean Squared Error (RMSE) values of 0.1338 and 0.1869, respectively.
