摘要
本文将EPSM算法与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 5 .37时超声速平头圆柱绕流 ,并与DSMC结果进行比较 ,证明了DSMC/EPSM混合算法的有效性 ,并对两种算法的计算效率进行了比较。
The Equilibrium Particle Simulation Method (EPSM) is combined with the direct simulation Monte Carlo (DSMC) method to produce a hybrid DSMC/EPSM method which could handle flows in the transition regime between rarefied gas flows and fully continuum flows. The supersonic flow past a flat nosed cylinder is calculated by using the DSMC method and the hybrid DSMC/EPSM method. The result of the hybrid DSMC/EPSM method is compared with the result of DSMC method to show the effectiveness of the hybrid DSMC/EPSM method.Computational efficiency of these two methods is compared.
