真空小喷管羽流场的Monte Carlo直接模拟

MONTE CARLO DIRECT SIMULATION OF SMALL NOZZLE PLUME IN VACUUM

利用直接模拟的MonteCarlo方法数值模拟了真空喷管羽流场，获得了符合规律的数值模拟结果。由于将随机取样频率法（R－S－F）用于轴对称问题中，解决了计算机内存和速度上的困难，同时也证明了R－S－F方法的可靠性。

Vacuum plume problem is a important research problem puzzling astronautics designers, specially for communication satellites and space station. This paper adopted DSMC methods numerically to simulate vacuum plume of small nozzle, and gained corresponding results. This work is a good begining for further research on vacuum plume contemination, and referential to engineering design.
