Abstract
The mechanism was analyzed for the influences of high acceleration on the internal flow field and the ablation of insulator of SRM. A new method was developed which included two parts. The first part was to solve the three-dimensional two phase flow field of SRM under high acceleration condition by numerical simulation method and the second was to establish the ablation model of insulator by ablation experiment using flow field simulation equipment. Based on these studies the technique of insulator design and ablation prediction for SRM under high acceleration condition can be developed. The key technique is to develop a flow field simulation experimental method. Several projects were discussed and the siphon device seemed to be more feasible. To demonstrate the feasibility of this method, two phase flow field in siphon was analyzed by using numerical simulation method. The results show that the siphon device can congregate particles to generate two phase flow with high density particles.
