This paper presents a combined approach to study the impact of the structure of
cellular materials on their transport properties. This work is based on the use of the
morphological 3D analysis software (iMorph), to precisely characterize the geometry of
cellular solids, extensive experimental characterization at sample scale and numerical
simulation of heat and mass transfer at pore scale. With these approaches, and the study
on a wide range of metallic foams, we identify the geometrical relevant criteria for the
single and two-phase flow properties understanding.
Keywords: Single and two phase flow laws, effective transport properties, metal
foams, X-ray tomography, 3d images, morphology, representative elementary
volume (rev), numerical simulations, finite volume, lattice boltzmann.
