Macroscopic equations are a practical tool for numerical modeling of physical processes in components based on porous media. In this study a set of macroscopic equations is presented including the effective material properties to model the fluid dynamics and heat transfer in open porous metallic foams in high heat load applications. The model is validated in a test campaign using a high radiation flux test facility. In addition the model is used to assess the potential of open porous metallic slip-reaction-foams based on a high temperature resistant nickel alloy in the application as effusion cooled combustion chamber wall elements. The analysis shows promising results even though the cooling efficiency has not yet reached a satisfying level.
