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 ...
It is important that porous metal foams used in gas turbines do not exceed their upper temperature threshold. In this paper, the Transient Plane Source (TPS) technique was used to measure the thermal conductivity of metal foams up to 1000 °C. Results showed that the thermal conductivity values for porous metal foams were lower than dense metals by a factor of 20-40....
