A numerical study is conducted to study the effect of aspect ratio (extending the height) on the natural convection flow inside a square cavity. 2D incompressible equations are solved using the open CFD package OpenFOAM. A domain and grid independence study is conducted for getting the optimum dimensions and the grid size used in the problem. The validation is done for benchmark problems before applying on to the problem. The vortices formed inside the enclosure is identified by the help of streamlines. This paper clearly discusses the different regimes formed by changing the aspect ratio.
