Abstract: With DSMC method employed to model the movement of solid particles and N-S equation solved with NND scheme, the 3D supersonic gas-solid two-phase conduit flow is numerically simulated. The effect of solid particles on flow field structure is analyzed. The results demonstrate that combination of DSMC method with CFD is an effective approach to solve the gas-solid two-phase flow problem.
