Abstract
The transient buoyancy-driven convection in a water saturated porous cavity is studied numerically. The left vertical wall is considered into three different partially heating locations. The Brinkman-Forchheimer extended Darcy model is used to investigate the average heat transfer rate. The governing equations are solved using the finite volume method. The results obtained for various values of parameters are presented graphically in the form of streamlines, isotherms, and velocity at the mid-plane of the cavity. In addition, numerical results for the average Nusselt number are presented for various parametric conditions. It is found that the heat transfer rate is enhanced when the heating location is at the bottom of the cavity for increasing value of temperature.
