Abstract
In this work, a numerical simulation of steady and laminar free convection flow over a heated vertical flat plate embedded in a saturated porous
medium by a Newtonian fluid is presented and analyzed. The Brinkman-Forchheimer extension of Darcy’s law has been adopted to describe the
movement of fluid within the porous matrix. A numerical solution of the governing continuity, momentum and energy equations was made with the
appropriate boundary conditions using ANSYS/FLUENT software based on finite volume method. The found results are graphically presented and
physically discussed for main controling parameters. Subsequently, we compared our CFD calculation by the results obtained with the similarity
method in terms of temperature profiles for selected values of the Rayleigh number. It is essentially found that the increase in the Rayleigh number
promotes the flow and the transfer of heat by convection in the porous medium.
