A method of simulation of a gas-solid two-phase flow of intermediate concentrations is developed. Particle diffusion due to inter-particle collision is treated by using the Direct Simulation Monte Carlo method. Four existing schemes of the DSMC method are compared and it is concluded that the Belotserkovskiy-Yanitskiy (B-Y) scheme is suitable for treatment of inter-particle collision in solid paricle systems. Particle collision with the solid wall is simulated by a semiempirical collision model. The gas flow is calculated by solving the compressible Navier-Stokes equation using the third-order accuracy upwind QUICK scheme and Reynolds stress turbulence model. This model is applied for "saltation" state particulate flow in a bend of a three-dimensional rectangular duct, and the calculation results are shown.
