The effectiveness of metallic foams in forced convection heat removal is studied. The metallic foam showed an improved heat removal rate with a moderate increase in the pressure drop. The hydraulic and thermal characteristics are analyzed experimentally. The measurements are used in conjunction with a model based on a bank of cylinders in cross-flow to understand the effect of various foam morphologies. The model prediction is extrapolated to examine the trade-off between heat removal and pressure drop. For a particular working fluid, the model provides two sets of design parameters; (i) a preferred foam morphology which will provide the required heat flux at a competitive pressure drop and (ii) the circulating fan characteristics as an output flow rate vs. the static pressure drop.
