A numerical scheme based on the control volume method to solve conjugate heat transfer problems in a system consisting of porous media and bounding walls has been developed using a two-energy equation model for porous insert. Appropriate wall heat flux expressions for the fluid phase and solid phase were obtained from the proposed heat transfer model at the interface between porous media and solid wall. The heat transfer model clarifies physics of the known thermal boundary condition at the interface. Predicted interface temperature distribution and Nusselt number show very good agreement with the available experimental data for the case of using metal foams as the porous insert. Effect of wall thickness on heat transfer to the porous media has been investigated and the importance of considering heat conduction in the wall as well as heat transfer in porous media was demonstrated.
