| Abstract: | 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. |
