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.
