DSMC METHOD AND THE CALCULATION OF RAREFIED GAS FLOW
-
摘要: 直接模拟MonteCarlo(DSMC)方法是依赖物理的概率模拟方法.在求解过渡领域流动的众多解析、数值和模拟方法中,目前只有DSMC方法是可以模拟三维复杂真实气体流动的方法.从宏观参量到细观速度分布函数的水平上,该方法均能得到实验的支持.本文综述了DSMC方法的最近发展,包括我们在检验模型、处理内能松弛模拟和化学反应模拟以及求解三维绕流的通用方法等方面的工作。

Abstract: DSMC method'is a physically based probabilistic simulation method. Among the numerous analytical, numerical and simulative methods, DSMC method is the only Procedure capable of simulating the flow of real gas with complex three-dimensional configurations. The method is supported by experiments both on the level of global macroscopic characteristics and the level of microscopic characteristics such as the velocity distribution functions. The present paper reviews the recent development'of the DSMC method, in...
