Abstract: This paper reports the results of a numerical analysis of the influence of various parameters for the combined free and forced convection problem in a vented cavity with a centered heat generating element. Forced convection flow conditions are imposed by providing an inlet at the bottom of the left vertical wall and an outlet opening at the top of the opposite sidewall. Numerical solutions of the considered governing equations for the present study are obtained using the finite element method. The influence of Hartmann number, Prandtl number and Reynolds number on the flow and thermal fields is carried out and findings are presented by the streamlines and isotherms. Moreover, the heat transfer characteristic of the enclosure is displayed in terms of average Nusselt number and the dimensionless average bulk fluid temperature. Based on the computational results, it is noted that the studied parameters play a significant role on both the flow and thermal field.
