| Research Abstract |
A debris flow is one of the solid-liquid multiphase flows, in which the solid (soil) and the liquid (water) interacting each other move with a free surface. The behavior of the debris flow is too complex to predict. In the present study, a numerical scheme is developed to predict the solid-liquid flow with the free surface. In this scheme the DEM (Discrete Element Method) is coupled with MPS (Moving Particle Semi-implicit). The present scheme can be extended to a prediction system of dangerous region at the occurrence of the debris flow.
