In this study, solid-liquid flows with coarse particles, which form a highly concentrated zone in a pipe, were simulated. In general, the cell size of the continuous phase is larger than the particle size. However, with increases in particle size, the cell size must be close to the particle size in order to maintain high resolution of the fluid velocity. Simulation using equal cell and particle sizes was carried out to investigate the effects of fluid velocity, pressure gradient and void fraction on the settling motion of a particle in rest water. For simulating a particle cloud, a conventional Lagrangian/Eulerian method using the drag coefficient of a particle cloud was employed. The results so obtained were compared with the results using the drag coefficient of a single particle under the same flow and particle conditions.
