A two-dimensional coupling model of the discrete element method (DEM) and the lattice Boltzmann method (LBM) was used to study the fluid flow through porous media. The fluid flow was modeled at a mesoscale level by using the LBM. The particle motion was modeled at microscale level by means of the DEM. The interfacial interaction between the fluid and the solids is resolved by an implicit immersed...
