Abstract

Simulation of air and water flow in deformable porous media and comparison with experimental data Z. Xiaoyong", L. Dai# Li Danli (Guangzhou Normal Institute, China) ABSTRACT The behaviour of multiphase liquid flow in deformable soil is described by a coupled set of PDEs, including equilibrium equation for soil phase and continuity equations for wetting and non-wetting fluids respectively. The governing equations are solved by finite element method to give a description of air and water flow in a laboratory column with porous medium deformation. Comparison with experimental data is shown with well agreement. INTRODUCTION Traditional descriptions of water movement in unsaturated porous media are based on single phase fluid flow in rigid soil skeleton. Numerical simulation following this idea has produced significant scientific contribution to the application fields of water resources, in addition to the experimental works in the laboratory and field.
