The thermal transport characteristics of metal foams have been
studied in the past several decades to a significant extent [4–8].
Calmidi and Mahajan [4] measured their effective thermal conductivity
by setting low temperatures in the two-dimensional structure
analytical model while ignoring the effects of thermal
radiation. Later, Boomsma and Poulikakos [5] developed a threedimensional
idealized cellular structure model for predicting the
effective thermal conductivity of metal foams. Hunt et al. [6] and
Hsu et al. [7] investigated thermal dispersion phenomena in porous
metal media. Both papers revealed that high heat fluxes could
be easily dissipated in metal foams. The boundary and inertia effects
on forced convection in metal foams were investigated by Vafai
and Tien [8]. They found that inertia effects were not negligible
in high velocity fluids. Lu et al. [9]
