摘　　要：在研究现有的两相流数学模型的基础上,引入多点同时碰撞的概念,提出了1种新的颗粒碰撞数学模型,并结合直接Monte-Carlo(DSMC)方法对水平通道内气固两相流进行了数值模拟,再现了颗粒团的存在。Based on the concept of simultaneous multipoint collision and the current mathematical models, a new mathematical model of inter-particle collisions is proposed. The gas-solid＇flow in horizontal duct is simulated with Monte-Carlo （DSMC） method. The computational results indicate interparticle collisions results in nonuniform distribution of particles and formation of clusters. In comparison with other scholars, the numerical results are generally consistent with their data.
