Abstract: The effect of radiation losses on the natural convection heat transfer from metal-foam of convex

parabolic profile is studied analytically and numerically. Two models, with and without effect of

radiation, are introduced based on using energy balance and Darcy’s model to formulate the heat

transfer equation. Air and Aluminum are employed as the cold fluid and porous medium, respectively,

and the effects of radiation, pore density (PPI), Rayleigh number (Ra) and porosity on the heat transfer

rate are studied in detail. The results show by increasing PPI and decreasing Ra the heat transfer rate

decreases as permeability decreases.Furthermore, the effect of porosity on heat transfer without

radiation is negligible, but the effects of radiation is considerable in rising heat transfer rate.
