  • The effect of using scrap tire powder in the perforated brick holes on
           thermal insulation

    • Authors: Husam Jasim Farhood, Alaa Liaq Hashem
      Pages: 075 - 082
      Abstract: In this study, old scrap tire powder was used with building materials commonly used in Iraq, where it was used in some brick holes in the form of powder 0-1 mm ( crumb rubber without fabric and metal), and this case, it was called scrap tire powder in bricks [STP-I]. It was compared with the traditional wall that does not contain scrap tires, called [No STs]. A test room has been build prepared for this purpose and a heating source for 8 hours applied on each wall. The comparison was by measuring the temperatures on the inner and the outer surfaces as well as the center of the wall, and comparing the thermal resistance and the heat transferred. The results noted that the addition of this material might be reducing the internal surface temperature by 2.56℃, which is a good incentive for this material's role as a thermal insulator.

  • Structural behavior of lightweight reinforced concrete columns exposure to
           eccentric loads at high temperature

    • Authors: Faaiza Hassan Al-Naqeeb, Haitham Al-Thairy
      Pages: 083 - 091
      Abstract: This paper presents an experimental investigation on the behavior of six   reinforced concrete columns under elevated temperature. An expanded clay aggregate (LECA) was used in three reinforced concrete columns ,other three remain columns used natural aggregate .All RC columns have similar cross sectional dimensions of 150mm ×150 mm (width× height); and 1250mm total length. The columns were designed according to ACI Committee 318-2014 and exposed to different elevated temperatures of 400 oC and500 oC. After exposure to elevated temperature, the columns were axially loaded by compression force using an eccentricity ratio (e/h) equal to 0.5. The experimental test  results demonstrated a remarkable decrease in the ultimate carrying capacity of the columns when subjected to elevated temperature. The experimental test results have also revealed that the lightweight reinforced concrete columns have more fire resistance than the normal weight reinforced concrete columns under same elevated temperature. The ultimate load capacity of LWRC columns decreases by about 6.5 % ,and 14.286 %, at elevated temperature magnitude of 400 ºC, and 500 ºC respectively, compared with the control column at ambient temperature. However, the ultimate load capacity of NWRC columns decreases by about 14.15 %,and 28.571 %, at elevated temperature magnitude of 400 ºC, and 500 ºC respectively, compared with the control column at ambient temperature.

  • Enhancement of Airfoil Performance by Rotating Cylinder

    • Authors: Mohammed Sadeq Kadhim, Dhafer A Hamza
      Pages: 092 - 098
      Abstract: This study used a NACA 6409 smooth wing section. Its performance is compared to an enhanced design incorporating a revolving cylinder on the upper airfoil surface. The boundary conditions for the present work were Reynolds (105), and the attack angles were (0,2,4,6,8,10,12,14,16). A turbulence model was developed (SST K-), one of the aerodynamics models. This model is well-suited for sensing flow near a wall. The cylinder was evaluated at three positions (25,50,75) percent of the chord's length. The results indicated that position (25 percent C) was optimal, as it resulted in a 24.45 percent increase in lift coefficient at the angle of attack (12). And when the results were compared to those of other studies, they revealed a significant agreement.

  • The effect of ribs spacing on heat transfer in rectangular channels under
           the effect of different types of heat flux in the Presence of a nanofluids
           

    • Authors: Haneen Mohammed Sadiq, Naseer Hameed Hamza
      Pages: 099 - 108
      Abstract: In this study, numerical computations of the influence of adding ribs in a rectangular channel on the forced convection heat transfer and laminar fluid flow characteristics has been carried out. The analysis was carried out by using the finite element method to solve the dimensionless governing equations for two-dimensional channel with 80 mm height and 2000 mm length at the Reynolds number of (10, 100, and 500), rib height e=8mm with different aspect ratios (AR =2.5, 3.125, 3.75, 4.375, and 5). Also, the study compared two cases of investigations with and without nanofluid (Water/ TiO2) at the volume fractions of nanoparticles of 0, 2 and 4%. The results concluded that, for a certain arrangements, the use of extended surfaces within a rectangular channel can significantly enhance the rate of heat transfer and when the aspect ratios decreases, the Nusselt number increased. However, the existence of ribs within channel in case of constant heat flux can cause a significant improvement of heat transfer compared to that in the corresponding channel under the variable heat flux.

  • Application of LES/PDF and RANS/PDF approaches for simulation of spray
           combustion

    • Authors: Duaa Yaseen Haran, Ahmed Abed AL-Kadhem Majhool
      Pages: 109 - 116
      Abstract: This paper is addressing of a coupling Large-eddy simulation (LES) and RANS turbulence models with mixture fraction/probability density function as a combustion model. The two models have been implemented to simulate ethanol-air spray combustion. The gas phase is described with the Eulerian approach while the liquid phase is designed using a Lagrangian framework. The LES/PDF approach is obtained statistically. The sub-grid scale energy equation is used with the LES/PDF approach. The numerical results are validated with experimental data. Both LES/PDF and RANS/PDF approaches are compared with the experimental data. The LES/PDF approach shows a good agreement in predicting the average gas temperature compared with RANS/PDF approach. The LES/PDF shows a better prediction of both turbulence intensity profiles and the vortices which are generated in the turbulent flow in comparison with the RANS/PDF approach.

  • Temperature Change in Steel-Concrete Composite Bridge: Experimental and
           Numerical Study

    • Authors: Maryam Salim Awad, Muhaned Shallal
      Pages: 123 - 133
      Abstract: In this article, a prototype empirical section of the composite girder was performed to verify the temperature distributions and the changes in concrete bridges under environmental thermal stresses. T-Beam composite section was placed directly subjected to environmental conditions to endure the change in convection, the convection includes solar radiation, surrounding air temperature and wind speed. In addition, this paper includes the 3D finite-element thermal studies represented by the COMSOL MULTIPHYSIC program, with particular reference to the influence of several parametric studies that represented by changing in concrete thickness, adding asphalt layer and finally change the value of wind speed. The section is prepared with fifteen thermocouples in different places in steel and concrete in the actual and theoretical model to evaluate the temperature distribution inside the composite bridges and their effects in the selected points. COMSOL MULTIPHYSIC showed a good ability to simulate convection, heat conduction and radiation within the surrounding environment. Such as thermocouple (TC3) the minimum temperature was 33.18 oC, 33.29 oC, the maximum temperature was 63.67 oC, 62.77 oC for experimental and theoretical results respectively while the maximum and minimum difference between experimental and FE temperatures is 2.96 and 0.099 for TC3 respectively. Therefore, it can be said that all the thermocouples results showed a good agreement between practical and theoretical results.

  • Treatment of Al-Dewaniya hospital wastewater by Electrocoagulation method
           using SS/Fe electrodes.

    • Authors: Riham Ghanim Najeeb, Ali H Abbar
      Pages: 134 - 143
      Abstract: The present study focused on the treatment of hospital wastewater generated from Al-Diwaniya hospital located at Al-Diwaniya city/ southern Iraq via an Electrocoagulation (EC) process with SS/Fe electrodes. Response Surface Methodology (RSM)  was used to evaluate the main effects of parameters, their simultaneous interactions and quadratic effect to achieve the optimum condition for EC process. Chemical Oxygen Demand (COD) was observed and measured for each experiment as it can be used as a good indicator of the quality of wastewater. The impacts of three factors such as current density (5-25mA/cm2), pH (4-10), and addition of NaCl(0-3g/l) were evaluated. The obtained experimental data were fitted to a second-order polynomial equation with analyzing by variance analysis (ANOVA).  The results shown that current density has the major impact on the efficiency of COD removal followed by addition of NaCl while pH has the lower effect on the COD removal under the studied range of pH. ANOVA results showed that the determination coefficient of the models was R2 98.18% confirming that the quadratic model was significance with a good fitting between the experimental and predicted results.  The optimized operating parameters were a current density of 25 mA/cm2, pH of 7.8,and NaCl addition of 3 g/l in which COD removal efficiency of 97.14% was achieved with a specific energy consumption of (30.914) kWh/kgCOD.
