Abstract: 

In the present paper, three dimensional turbulent mixed convection inside the ventilated cavity is solved using by Large Eddy Simulation (LES) and the results are validated with available numerical and experimental ones. In the present work, the forced convection and free convection are due to the injected flow from ventilation system and temperature difference among floor and other walls of cavity, respectively. The effects of obstacle on flow characteristics such as velocity, temperature and turbulent kinetic energy are investigated for cavity flow containing obstacle with three different height. In continuation, effect of obstacles on coherent structures are investigated by applying the proper orthogonal decomposition (POD) algorithm on velocity fluctuation field in x direction. From the results, firstly, obstacle causes to increase the energy of coherent structures, and secondly, obstacle with large height break the coherent structures to smaller ones, but for obstacles with medium and small height dominant structures are enlarged.
