Influence of orientation and radiative heat transfer on aluminum foams in Buoyancy-induced convection [PDF]

open access: yes, 2015
Two differently-produced open-cell aluminum foams were compared to a commercially available finned heat sink. Further, an aluminum plate and block were tested as a reference. All heat sinks have the same base plate dimensions of four by six inches.
