Abstract

We here treat a diffusion problem coupled with water flow in bentonite. The remarkable behavior originates from molecular characteristics of its constituent clay mineral, namely montmorillonite, and we show the behavior based on a unified simulation procedure starting with the molecular dynamic (MD) method and extending the obtained local characteristics to a macroscale behavior by the multiscale homogenization analysis (HA: Sanchez-Palencia, 1980). Not only the macroscale effective diffusion property but also the adsorption behavior is well defined based on this method.
