The fluid flows around large solid particles are numerically visualized. The liquid flows and particle motions are predicted with a fluid-based distinct element method (F-DEM). The F-DEM is based on the CFD technique for incompressible flows, in which the treatment for density and mass conservation have been improved in the collocated grid. The external forces for the particles are evaluated from the results of the fluid computations and from a model of the distinct element method. It was shown that the particle motions as well as the unsteady liquid flows caused by falling particles in a finite area are reasonably predicted with the present F-DEM.
