| 摘 要： | 文章通过DSMC(Direct Simulation Monte Carlo,直接模拟蒙特卡罗)方法对卫星发动机羽流进行数值模拟,对仿真方法进行了对比验证,证实了DSMC方法可以比较精确地模拟羽流场.在建立卫星污染模型的过程中,针对污染发动机喷口形状的变化以及出口参数的变化,对DSMC方法模拟结果进行了对比,得到喷口形状和出口参数的变化对模拟结果的影响,并得到最优的卫星敏感表面羽流污染计算模型.

| Abstract: | To study satellite thrusters for attitude control and orbit control, the DSMC method is used for plume contamination modeling on satellite sensitive surfaces, in simulating nitrogen plume flow, and the results are compared with those of existing experiments. The reliability of DSMC method for the plume simulation is verified. Then, the results of the DSMC simulation are compared for different model parameters of plume contamination, which may offer references for studying plume back flow contamination on the sensitive faces. |
