Abstract
The mass diffusion process inside a porous medium is difficult for numerical simulation due to complex and stochastic nature of its structure. Based on the lattice Boltzmann method and reconstruction technology, this article presents an approach for simulating mass diffusion process and predicting the effective mass diffusivity in porous media, which is validated by comparing theoretical and experimental data. The concentration distribution and effective mass diffusivity inside porous media can be obtained.
