Abstract : A two-dimensional turbulence k-? model is used to predict the distribution of air velocity, temperature and turbulence kinetic energy in a ventilated room using different positions of inlet and outlet apertures. The Navier Stockes, energy and turbulence equations are solved using finite volume techniques with staggered grid. The characteristics of air flow are analyzed under different parameters such as inlet and outlet positions, aspect ratio and air supply velocities. This study is focused on the prediction of turbulent recirculating flows in large indoor spaces. The results show that the wall jet region and recirculation regions are affected by the position of inlet and outlet apertures. Also the results indicate that recirculation regions are increased with increasing Reynolds number and decrease with decreasing aspect ratio.
