The main research outcomes were as follows : ( 1 ) the paper applied quasi - three dimensional design model and optimization design model based on si flow surface that was effected by runner ( impeller ) and guide vane jointly. the vortex flow, blade thickness limitation and runner ( impeller ) blade force functions were taken into account. the paper got the improved runners of hl240 type, which were runner hlx240d and runner hlx240e
主要成果有: ( 1 )應用考慮轉輪來流有旋、葉片有限厚及轉輪(葉輪)葉片力作用的轉輪(葉輪)與導葉聯合作用的基於s _ 1流面的準三維設計模型和優化設計模型,研究出了hl240的改進型轉輪: hlx240d和hlx240e 。
