Abstract
Gas-solid two-phase flow in the nozzle was numerically simulated by using stochastic trajectory model, and two kinds of calculation results with stochastic trajectory model and determined trajectory model were analyzed and compared with experimental measurement results. For different solid-phase parameters (solid-phase mass ratio, particle mean diameter) performances of solid rocket motor nozzle were investigated. It is found that stochastic trajectory model is superior to determined trajectory model in two-phase flow field simulation. Two-phase flow loss increases and impulse coefficient decreases with the increase of the solid-phase mass ratio and particle mean diameter.
