.... convection heat sink metal foam graphite foam electronics cooling Commercially produced metal foams are typically made from aluminum, nickel, steel, copper, and some of their alloys. These materials are known to have high thermal conductivities. This class of porous media has many practical...

...Sheng-Chung Tzeng; Tzer-Ming Jeng This work experimentally and numerically investigates the heat transfer in uncompressed∕compressed metal foams. Experiments were conducted to obtain the thermal characteristics of a rectangular channel filled with aluminum foams using air as the fluid medium...

...A. Bhattacharya; R. L. Mahajan In this paper, we present our recent experimental results on buoyancy-induced convection in aluminum metal foams of different pore densities [corresponding to 5, 10, 20, and 40 pores per in. (PPI)] and porosities (0.89–0.96). The results show that compared to a heated...
