| Abstract: |
| The present study is a part of the research work on the fluid transients in turbopump fuel system.The high speed pictures taken for fluid transients occuring in pump suction side and discharge side are compared with the results of measurements in transient process. Special attention is directed to the analysis of the mechanism of separation and gas-liquid two-phase flow caused by fluid transients as well as their influence upon the performance of turbopump fuel system. Some measures for preventing turbopump fuel system from damagement are suggested. |
