| Abstract: | 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. |
