Abstract

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.
