| Abstract: |
| he axial symmetric low density flow field of small nozzle is simulated numericallyby using DSMC method.The results conform well with ones by differential solving N-S equations.This work has deep background of engineering application and is very imporuant to the situationcontrolling rocket motor design for communication satellites and space stations. |
