| Abstract: | A fully coupled two-phase viscid nozzle flow of SRM is numerically simulated with FLUENT software. The velocity, temperature and trajectory of the particles are treated with Lagrangian approach. The gas that contains the combination of five classes of particles was tested and calculated. The results indicate particle distribution influences flow field significantly. |
