X-ray computed tomography and numerical analysis of water-saturated porous materials

Abstract

A method for imaging a water-saturated porous material is developed in order to simulate a fluid flow through it using the Lattice Boltzmann method. The value of its flow permeability is compared to the value for the same sample when it is dry. An explanation for the difference in the experimental values of permeability for air and water is sought. A reference is given by experimental values from flow measurements that are interpreted according to Darcy's law of permeability.
