Liquid-solid two phase channel flow has been simulated by a large eddy simulation. Calculations were performed at channel flow Reynolds number Re_τ=150 based on friction velocity and channel half width. Flow parameters and particle properties are identical to those in the experimental measurements of HISHIDA et al. The interaction between fluid turbulence and particle motion is treated by two-way coupling method. The numerical results for the fluid turbulence modification due to particles were compared with the experiments. It is shown that reasonable agreements were obtained between the simulation and experiments.
