Abstract

Numerical simulation of gas-solid two-phase flow in jet thrust vector nozzle was carried out using particle trajectory model based on shock wave control. The simulation results were compared with that under the situation of pure gas. The particle track, parameters in internal flow, as well as the thrust performance were studied when particles' diameter changed in the range of 1~ 40µm. The results showed that the addition of particle had certain influence on both internal flow field and thrust performance of vector nozzle. Moreover, the change of particle diameter could affect these characteristics. Therefore, these influences must be taken into consideration for nozzle design and research.

Key words： solid rocket motor; jet thrust vector nozzle; two-phase flow; particle trajectory model; numerical simulation
