摘要：
The problems of fluid flow in porous media have an important researchful value and many applications to engineering thermophysics. In this paper, the multi-relaxation-time lattice Boltzmann method is used to predict permeability of two kinds of two-dimensional porous media. The results show that, on one hand, some shortcomings of single-relaxation-time model can be overcome by multi-relaxation-time model, and on the other hand, with aid of Darcy's law, the permeability of porous media can be predicted correctly by multi-relaxation-time model. The numerical results are compared with some available works.
