摘      要：In this work,computational fuid dynamics(CFD)is used to study elbow erosion due to a gas-solid two-phase *** particular,the direct simulation Monte Carlo(DSMC)method is used to study the impact of inter-particle collision on the erosion *** two-way coupled Euler-Lagrange method is used to solve the gas-solid fow,and the DSMC method is used to consider the collision behavior between *** efects of key factors,such as the particle concentration distribution and inter-particle collision,on the erosion ratio are evaluated and *** efectiveness of the method is verifed from experimental *** results show that the inter-particle collision signifcantly infuences the particle movement path and erosion *** the inter-particle collision is considered,the maximum erosion position is *** erosion model proposed by Oka et al.,who used the DSMC method,agrees best with the experimental data,and the average percentage error decreases from 39.2 to 27.4%.
