Convection heat transfer from aluminium and copper foams in a vertical channel - An experimental study

► Experimental investigations in a vertical channel filled with a metal foam. ► Fluid flow and heat transfer characteristics studied for a range of parameters. ► Foams made of copper and aluminium, 10 to 30 mm thick, used in the studies. ► Correlation developed for average Nusselt number. ► Foams seen to give high thermal performance for a small increase of pressure drop.
