Application of Micro Computer Tomography to Identification of Pore Structure Parameters of Porous Materials

Abstract

The purpose of this paper is to apply the scans of microscopic geometry of human bones obtained by Micro Komputer Tomography method to identifi cation of their macroscopic pore structure parameters: volume porosity, permeability and tortuosity of pores and skeleton. These parameters, except the volume porosity, have been determined by simulations of microscopic processes of viscous fl uid fl ow and electrical current passage through virtual models of bones samples. The simulations wave performed using the COMSOL’s Multiphysics environment assigned for solution of boundary value problems described by partial diff erential equations, by use of the fi nite element method
