To examine eddies around solids in multi-phase flow, a high-resolution calculation is needed. But, it is difficult to calculate the unsteady flow with solid phases, in particular, there are few methods that can simultaneously deal with free surface comprehensively. MPS method is effective to capture interface between phases and free surface even in violent flow. Despite of this advantage, MPS method doesn't have enough schemes to treat flow around solid with high resolution. In this study, three new schemes of DEM-MPS method for high resolution calculation of solid-liquid multi-phase flow are proposed and their validities are verified by comparing their results with an experiment of 2D multi-phase dam-break with cylinders.
