Forced convection heat transfer in metal foams in the presence of radiation heat transfer is studied using the homotopy perturbation method (HPM). To see wall effects, Darcy-Brinkman model for the flow in porous media is used. A constant heat flux is imposed at the wall and the radiation heat transfer is modeled by a temperature-dependent conductivity. In the present study the case of conjugate convection and radiation heat transfer is analyzed by a semi-analytical approach for the first time. Effects of the radiation parameters (Î», Tr) and porous medium shape parameter (s) on the Nusselt number and dimensionless temperature profile are investigated. Moreover, a discussion on the accuracy and limitations of the HPM method will be presented.
