Abstract
The paper presents comparison between numerical and experimental results to verify finite element algorithm of air diffusion in three-phase porous media. The theory of two-phase flow in partially saturated soil is a fundamental study to predict the safety for $CO_2$ sequestration. Geotechnical engineering problems exposed to atmospheric pressure generally assume that air pressure is equal to zero in three-phase porous media, but the geotechnical engineering problem at a depth of about over 1 km needs to be considered in connection with deformable solid skeleton due to air pressure. Therefore, the objective of this study is to validate the numerical algorithm by comparing with results obtained from measurement of air diffusion and dissipation through drainage test.
