| Abstract: |
| fitting formula for particle size D43 in solid rocket nozzle two-phase flow was developed by using multivariate least square method, which will be used as a criterion for prediction of solidrocket motor performances. |
| Key words: Nozzle gas flow Two phase flow Granularity Fitting function |
