Abstract

We propose a numerical method for handling interaction among multiple particles, fluid and structure of arbitrary shape. The method is based on the level set method, the DEM (discrete element method), the CIP (Cubic Interpolated Propagation) method and the ghost fluid method. In this formulation, interfaces of particles, liquid and structures are represented by the level set functions. Those level set functions are also used to impose fluid boundary condition on structure and particle, and to detect collisions between particle and structure. Numerical results show that this proposed method can robustly simulate those interactions.
