摘　　要：将平衡粒子模拟方法(EPSM)与蒙特卡罗直接模拟(DSMC)方法结合,构造了可模拟含近连续流区及过渡流区的DSMC/EPSM混合算法.运用混合算法模拟马赫数等于10时高超音速竖板绕流,并与DSMC结果进行比较,证明了DSMC/EPSM混合算法的有效性.The equilibrium particle simulation method (EPSM) is combined with the Monte Carlo direct simulation method (DSMC) to produce a hybrid DSMC/EPSM method which could handle flows in the transition regime between rarefied gas flows and fully continuum flows.The hypersonic flow past a vertical plate is calculated by using the DSMC method and the hybrid DSMC/EPSM method.The results show the effectiveness of the hybrid DSMC/EPSM method.
