The aim of this article is to study numerically the influence of the physical parameters of the porous medium on the heat transfer rate. To do this, we use the Darcy-Brinkman-Forchheimer model, and a numerical tool (Ansys fluent) to solve the heat transfer and Navier-Stockes equations. The average Nusselt numbers (convective and radiative) were then determined as a function of thermal conductivity, porosity and permeability. We can deduce that as thermal conductivity increases, the heat transfer rate rises to a maximum value before decreasing. As porosity increases, radiative and convective Nusselt decrease. Finally, the transfer rate increases with increasing permeability.

Abstract
The aim of this article is to study numerically the influence of the physical parameters of the porous medium on the heat transfer rate. To do this, we use the Darcy-Brinkman-Forchheimer model, and a numerical tool (Ansys fluent) to solve the heat transfer and Navier-Stockes equations. The average Nusselt numbers (convective and radiative) were then determined as a function of thermal conductivity, porosity and permeability. We can deduce that as thermal conductivity increases, the heat transfer rate rises to a maximum value before decreasing. As porosity increases, radiative and convective Nusselt decrease. Finally, the transfer rate increases with increasing permeability.
