Study of transfer and flow in porous media in nonequilibrium

Abstract

3D Natural convection in partially porous media. The Study focused on transfers and flow in porous media in nonequilibrium. Darcy-Brinkman model's is adopted. Moreover the two-equation model is used to separately account for the local fluid and solid temperatures. A numerical method based on the finite volume method a full multigrid technique is employed. We find the impact of the conductivities ratio on the flow and the heat transfer.
