Abstract: Metal foams are materials composed of a solid grid with air-filled pores, and have applications in combustion chambers of gas turbines. In this study, the thermal properties of porous metal foams were tested to determine their usefulness in heating and cooling systems. The Transient Plane Source (TPS) method was used to measure the thermal conductivity of porous metallic foams. Because the porous foams were not as compacted as the dense forms, they exhibited a thermal conductivity that was lower by a factor of 20-40, and the foam with the lowest porosity had the highest thermal conductivity.
