A novel analytical model is developed to examine the temperature distribution of high porosity metallic foams. The foam is modeled as small fins, which results in a set of equations similar to those obtained in finite difference representation of the energy equation, from which foam temperature can be evaluated. These equations are solved simultaneously along with the energy equation for the fluid. The parameters needed to determine the performance of the foam are average strut length (dp) and strut diameter (df) which can be obtained from the knowledge of foam Porosity (ε) and Pore Density (PPI). To validate the analytical model, the temperature distribution of an Aluminum 6101-T6 alloy foam with porosity 92% and pore density (10 PPI) is measured in a wind tunnel for different air velocities. There is close agreement between analytical and experimental results.
