  • Using FLUENT to Supplement Theory in an Introductory Fluid Mechanics
           Course

    • Abstract: Publication year: 2019Source: International Journal of Hydraulic Engineering, Volume 8, Number 1John Weber, George N. Facas, Michael Horst, Monica SharobeamModeling software is becoming a valuable tool in undergraduate engineering education. Historically, computer programs were taught to students in design intensive courses, while introductory or fundamentals courses relied on the typical faculty led lecture format which was absent of any modeling applications or demonstrations. This trend is now changing as various engineering software packages are being introduced earlier in the curriculum as a tool to assist students in understanding the theory corresponding to a particular topic. This paper details the application of the FLUENT Finite Volume Modeling Software, in an introductory fluid mechanics course, to a segment of pipe which experiences a sudden contraction. Students were able to explore various fluid phenomenon including: the development of fully developed flow, the linear relationship between pressure drop and distance, minor loss coefficients as a function of contraction ratio, and visualization of the contracting flow field. Qualitative feedback from students has shown appreciation for being introduced to modern engineering tools that are used in the practice of engineering.
       
  • Influence of Wingwall Configuration on Outlet Scour at Bottomless Box
           Culverts

    • Abstract: Publication year: 2019Source: International Journal of Hydraulic Engineering, Volume 8, Number 1Michael HorstThe purpose of this study was to determine what influence the inclusion of wingwalls, of various types, located on the downstream side of a bottom box culvert, have on the magnitude of the resulting scour hole depths. Seven laboratory experiments were conducted with constant hydraulic conditions, each one with a different outlet configuration, and the resulting scour hole depths were measured. The results of the experiments showed the deepest scour holes occurred when there were either no wingwalls or when wingwall configurations were either at 45 degree angles or had a truncated circular beveled configuration. Conversely, the shallowest scour holes occurred when there was either a smooth wingwall placed on an 8 degree angle or a streamlined beveled wingwall configuration. Boundary roughness of the wingwall was also shown to influence the resulting scour hole depth.
       
  • Numerical Study of Natural Convection in a Vertical Channel, One of Whose
           Walls has Sinusoidal Protuberances

    • Abstract: Publication year: 2019Source: International Journal of Hydraulic Engineering, Volume 8, Number 1Gwendoli Djaomazava, Michel Aimé Randriazanamparany, François D’Assise RakotomangaA numerical study of the thermal natural convection applied in a vertical channel containing air, one of whose walls comprises a corrugated part subjected to a uniform heat flux of constant density, is the subject of this research. The work consists in characterizing the natural convection as a function of the height of the protuberances forming the undulations and the intensity of the heat flow, which crosses the corrugated wall. We analyze in particular the structure of the flow and the distribution of temperature inside the channel. Knowledge of different physical parameters on the behavior of the system can help to better understand its functioning and to integrate it effectively into practical applications such as, for example, passive climate control of building. The equations governing the transfers inside the channel are discretized by the explicit finite difference method, the results are illustrated using stream lines and isotherms, for a range of Rayleigh numbers from 5.103 to 5.105, for different values of the amplitude of the protuberances and for a number of Prandtl Pr = 0,71 for air.
       
  • Hydraulic Investigation of Air in Small Diameter Pipes

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 3Don May, James Allen, Danielle NelsonAir trapped in pipes is a serious problem resulting in reduced performance or complete blockage of flow in water systems. The minimum critical velocity needed to clear an air pocket from large diameter pipes has been studied but similar studies for small diameters is lacking. In this study, a series of laboratory tests are performed on 25 and 38 mm diameter pipes with 0°, 5°, 10°, 15°, 20° and 30° downward slopes. The relationship between critical Froude number and slope is determined for each diameter and found to be similar to those for larger diameter pipes. The critical velocity for the 38 mm pipe is found to be larger than that for the 25 mm pipe. The energy equation is used with pressure and flow measurements to estimate the head loss attributed to an air pocket. This value compared closely to the measured vertical height of the air pocket. Lastly, the velocity of an air pocket relative to the mean stream velocity is studied.
       
  • Flow Characteristics in Riffles by Using Boundary-layer Theory

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 3Mohammad Ghasemi, Hossein Afzalimehr, Vijay P. SinghPlanning and design of river engineering works depend on the changes in bed forms and their interaction with flow. This paper investigated the application of Coles law in the outer region of the boundary layer and compared it with the parabolic law on riffles; developed a relationship between Coles parameter and dimensionless pressure gradient β; determined the von Karman constant for the riffles; Results showed that the outer part of the boundary layer was represented by Coles law as well as by parabolic law, but not the inner part of the boundary layer. The pressure gradient parameter and the Coles parameter were not strongly correlated in general, but in the acceleration section they were. The von Karman constant, based on the shear velocity calculated by the boundary layer method, was close to the universal constant value of 0.4 and showed a slight variation along the bed.
       
  • Comparison of Performance of Simplified RANS Formulations for Velocity
           Distributions against Full 3D RANS Model

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 2Wisam Alawdi, T. D. PrasadSeveral analytical models of velocity distribution for turbulent uniform open channel flows were lately developed by analysis and simplification of the Reynolds-averaged Navier-Stokes equations (RANS). These simplified RANS-based models, which are called dip-modified laws, are frequently employed to predict the velocity profile in flow cases where the maximum velocity may occur below the water surface. In this paper, the performance of two simplified RANS models, namely the dip-modified log law (DML-law) and the dip-modified log wake law (DMLW-law) are compared against the full 3D RANS model used in the computational fluid dynamics (CFD) modelling. The results show that although the simplified RANS models can predict the velocity dip phenomenon, the accuracy of such models is less than the full RANS (CFD) model. This is likely to be due to the assumption imposed for approximating the secondary current term in the governing equations. It is also found that the DMLW-law can give results closer to that obtained by the full RANS model. This may because of including the wake effect in eddy viscosity calculation.
       
  • Potential Sediment within a Reach in Tigris River

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 2Thair Sharif Kayyun, Dheyaa Hamdan DagherThe length of the reach river for the study area is (19.5 Km) lies in Northern of Tigris river between Al- Muthana bridge and Sarai gauging station in Baghdad city in Iraq. HEC-RAS version (5.03) was employed by making use of recorded field measurements data for running, calibration and verification processes. A new equation for the rating curve was introduced to estimate the water surface elevation at the upstream and downstream of the river reach. This rating curve was created by using four flow rate scenarios (461, 890, 1815 and 2500 m3/s) in which water surface elevation ranging between 26.67 and 33.45 (m.a.s.l). For sediment transport analysis Laursen (Copeland) formula showed a good agreement with the measured field data. Changes in the river bed have been studied for the period from 2012 to 2017. The depth of erosion and sedimentation were calculated at the upstream and downstream of the river reach which are equal to 0.51 and 0.39 m, respectively. The cumulative average depth of the erosion of the river bed for the future period from 2017 to 2040 was estimated to be about 1 m for discharge of (461 m3/s).
       
  • Determination of Critical Depth to Avoid Free Vortex at Morning Glory
           Spillway by Numerical Modeling

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 2Hamidreza Rahimi, Erfan RazaviOne of the challenges facing the world today is the control and efficient use of water resources, which both of cases require accurate study and construction associated with it. But due to the high costs that are imposed during the study stages, design and especially execution to the government, the development trend of this important and fundamental infrastructure has been made difficult. So the initial study and finding the economic and most technical method is very important degree, so that today we live in a world that physical and non-physical models are intended as the ultimate decision maker and all the profits and losses of a thought, idea, and structure are put facing us. Morning glory spillway is one of water conveyance structures from the reservoir to downstream and is named due to its horny shape. Among the strength of morning glory spillway, is the ability to build in narrow valleys and embankment dams which usually has a spillway apart from the body. In general, morning glory spillway acts in free mode, with radial and axial velocity, so that in this mode the water flow is entered directly into the spillway, but during vortex phenomenon incidence and tangential velocity causes the flow path diversion of the direct mode and travel the longer path flow and so it makes of energy loss and the discharge capacity reduce. Therefore, one of the solutions to prevent this phenomenon is anti-vortex devices installation. In this study, from the obtained results of software outputs analysis and experimental data can be pointed out to the accuracy and validity of the model compared to its similar experimental model.
       
  • Determination of Conveyance Loss through Earthen Channel by Cutthroat
           Flume

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 1Rintu Sen, Maisha Fahmida, Irin Akter, MilufarzanaThe conveyance efficiency in irrigation projects is poor due to seepage, percolation, cracking, and damaging of the earth channel. Seepage loss in irrigation water conveyance system is very significant, as it forms the major portion of the water loss in the irrigation system. The purpose of this study was to determine the conveyance losses of irrigation water through earthen channel. A 50ft long and straight earthen channel was selected for this purpose. It was modified by excavation and compaction and also by maintaining suitable bed slope and side slopes. In this experiment discharge was measured by Inflow-Outflow method using cut-throat flumes. It can be seen from the results that conveyance losses were found to be 40.01%, 35.42%, 32.81% and 4% under natural condition, compacting the sides and bottom, using lining material of cow dung and rice husk mixture ratio 1:1 and polythene sheet, respectively. The results also indicated that lining material reduced conveyance loss to a great extent followed by compaction and natural conditions. It may be inferred that the mixture of cow dung and rice husk could be used as lining material because it is easily available, low cost and even unskilled labor can make it. Finally it could be used for reducing water losses through earthen channel.
       
  • Flow Characteristics around Wall-Mounted Circular Cylinder above the
           Horseshoe Vortex Region in Sub-Critical, Critical, and Super-critical Flow
           Conditions

    • Abstract: Publication year: 2018Source: International Journal of Hydraulic Engineering, Volume 7, Number 1Manar S. Al-SaffarThe relations between the flow characteristics around a circular cylinder have been investigated experimentally. The flow characteristics within three planes around a cylinder, mounted normal to the bed in an open channel, have been chosen for this study. Four different flow conditions were used in the study, changing from sub-critical to super-critical conditions. Two dimensional laser Doppler velocimetry was used to measure the instantaneous velocity components of stream-wise and vertical direction. The turbulent stresses of the flow field were calculated as a measure of the turbulent flow property criterion. The correlation coefficients between the turbulent stresses of points that are on the same height from bed within two different planes have been calculated as a measure for the relation between the different planes around the cylinder. A strong and stable relation has been found between the upstream and perpendicular profiles. Also, the spectra of the two velocity components time series at each of the measured points have been calculated, and similar peaks have been found in points with similar positions within the perpendicular and downstream planes. The results show existence of two different relations among the planes around the cylinder.
