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 is presented. 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 equations was made with the appropriate boundary conditions using ANSYS/FLUENT software based on finite volume method. The main obtained  results are plotted  graphically and analysed in details. Subsequently, we validated our CFD analysis  by comparing the obtained results to those of the similarity method in in term of temperature profiles for selected values of Rayleigh number
