英文摘要
A circumferential groove was adopted in the casing near the leading edge of the inducer to suppress cavitation instabilities in turbopump inducers for rocket engines. The circumferential groove could suppress the cavitation instabilities effectively. It was found that the cavitation instabilities with higher frequencies were generated by the interference of backflow vortex cavitation with the blades of the inducer. The dynamic characteristics of the inducer were estimated by computation and experiment.
