Improvements of Inducer Inlet Backflow Characteristics Using 3-D Inverse Design Method
The three-dimensional inverse design method was applied to improve the inlet backflow characteristics of highly loaded turbopump inducers for a liquid hydrogen rocket engine. Flow mechanisms, both for conventional and inverse design inducers, were investigated experimentally by flow field measurements and flow visualization, as well as numerically by the application CFD. The conventional inducer, which had been designed for the H-IIA rocket LE-7A engine turbopump, had a strong inlet backflow at the design point. Optimizing the blade loading distribution using the 3-D inverse design method and a CFD analysis eliminated this inlet backflow. Water model tests confirmed the elimination of inlet backflow in the inverse design inducers. However, it was confirmed that the suppressed inlet backflow tended to make cavitation occur in the blade passages and reduced suction performance. Cavitation visualization and FFT analysis of unstable phenomena were also performed in this study.
