Study of the porous material structure by computer-aided simulation

Abstract

The structure of porous materials and their permeability have been studied using computer-aided simulation within the porosity range from 0-99%. A sharp permeability increase is observed with the porosity interval 55-65%. The permeability has been show to be isotropic, i.e. independent of the porous structure filling direction within the whole porosity range. A classification of porous materials according to permeability has been proposed: low-porosity materials (0-5% permeability values), moderate-porosity materials (5-50% permeability values), high-porosity materials (50-95% permeability values) and super-porous materials (95-100% permeability values).
