摘要
本文分析了高空羽流流场的特性,论述了DSMC方法的原理以及涉及到的关键技术,应用DSMC方法数值求解了喷管出口附近及倒流区流场。仿真结果表明DSMC方法能够精确描述这一区域的流场特性。
In this paper,the character of high altitude plume flowfield is analyzed.The principle of DSMC method and its key points are also discussed.Then,the flowfield of nozzle exit vicinity and backflow region are calculated by using DSMC method,The results show that with this method,the flow property of this region can be accurately described.
