摘要：
In order to gain a better estimate of SRM slag accumulation, an Eulerian-Lagrangian two-phase approach was adopted to simulate the two-phase internal flow in a solid rocket motor with submerged nozzle. The two-phase flow field and trajectories of particles were predicted at six burn times, and slag weights (0.14%, 0.48% and 0.91%) retained in the back wall region of the submerged nozzle were calculated with three values (0.2, 0.4, 0.6) of Al2O3 re-attachable fraction. Some special treatments are suggested to reduce the slag accumulation.
