CONTINUUM MODELING AND SIMULATION OF MULTIPHASE DIFFUSION THROUGH A POROUS SOLID
Q. Zhao and P. Papadopoulos Math. Mech. Sol., 20, pp. 251-267, (2015)

Abstract
A theory is proposed for the continuum modeling of liquid and gas diffusion through a deformable porous solid. The solid and the voids are locally homogenized to yield a macroscopic solid phase. Liquid saturation of the voids and gas pressure are included as state variables to model diffusion. A model based on the proposed theory is implemented numerically using the finite element method, and tested with three simulations on sand and Nafion.
