Numerical simulations of the liquid-solid flow in a horizontal pipe were performed by the Lagrangian/Eulerian approach. Motion of individual coarse particles was calculated by the Newton’s equation of motion. The contact forces were given by DEM (Discrete Element Method)[1] model, which enables ones to estimate the forces on the moving particles in contact with their neighbors. The motion of liquid was calculated by solving the local averaged equations of continuity and motion. The calculated results showed the characteristic flow patterns of liquid-solid systems, such as flows with a moving bed or a deposit. The relation between the fluid velocity and the flow pattern agreed with the experimental results of sediment transport.
