Other Abstract In this paper, the improved CE/SE (the space-time Conservation Element and Solution Element method) scheme is extended to solve multi-phase flows in porous media. The hybrid particle level set method is used for tracing the interfaces of materials. The artificial compressibility method algorithm is selected to solve the pressure-velocity coupling. The model was developed by coupling an ordinary porous flow model based on extended Navier-Stokes equations for porous media, and a two-phase flow model. The resistance to flow caused by the presence of porous media was modeled in terms of drag and inertia forces. The dam break problem and falling droplet in a closed channel were calculated to validate the method employed in this paper. A model of dual lid-driven cavity flows in porous medium was also proposed as a benchmark problem.
