LBM模拟液体在多孔介质中的扩散

xp508508

如题，怎样用LBM模拟在多孔介质中的扩散啊？想得到由浓度梯度引起的扩散系数的值……这方面的资料不多，麻烦各位牛人提供些建议，不胜感激！

First of all, So far as the porous media are concerned, it is a matter of boundary conditions. As for the diffusion, there are LB models for multi-species which have self-diffusion and mutual-diffusion coefficients (cf. the papers by Luo & Girimaji, Asinari & Luo, and Asinari).
