We simulated the motion of spherical particles in a rotating rectangle vessel filled with water using an Eulerian/Lagrangian method. The collisions between particles and between a particle and a wall was calculated by DEM. The DEM for particles with uniform diameter was improved for those with size distribution. The volumetric fraction of the sphere to grid of fluid was taken into account, because the particles were large (the mean diameter was 12.53mm). The roughness of the wall of the vessel and the surface of the particle was taken into account for simulation. A comparison of results obtained by simulation and experimental observations showed acceptable levels in solidliquid flows.
