 note = {Investigation on compact design of rocket pump impeller and diffuser by using inverse design was presented. Two compact sizing, 95 percent and 90 percent of original design based on impeller and diffuser exit radius were investigated in this study. The performances and internal flow fields in the inverse designed impellers and diffusers were evaluated by Computational Fluid Dynamics (CFD) technique. The CFD results show the flow non-uniformity at the impeller exit tends to be increased from increased blade loading of compact design. The compact sizing of 90 percent of original design shows large penalty in performance at the 94 percent design flow by diffuser stall. The compact sizing 95 percent of original design showed a small performance penalty to original design in the range of 94 percent to 106 percent design flow rate, however impeller performance improvement compatible to the original design was expected by adopting wider impeller exit width and blade staking., 資料番号: AA0063736000, レポート番号: JAXA-RM-07-005},
