Computational study demonstrates that higher permeability enhances heat transfer in a partially porous chamber, indicating that layer thickness and permeability govern thermal convection.
This work is devoted to the study of heat transfer in a cubic chamber partially filled with a porous material by a single fluid. The mathematical model used is that of Darcy -Brinkman -Forchheimer. The modeled equations of continuity, motion, energy and mass are numerically solved by the finite volume method. The influence of permeability and other parameters on heat transfer has been studied. The results obtained show that Nusselt numbers increase with increasing permeability for different Darcy numbers, and decrease with increasing porous thickness. The numerical results of our study are in good agreement with those found in the literature.
