【摘要】 采用多元回归分析方法研究了轴流泵叶轮升力系数CY与参数半径比(任意半径与叶轮最大半径之比)r/rK、翼型相对曲率f/l、相对弦长l/t、翼型安放角β、冲角α和叶轮外缘径向间隙s对轴流泵叶轮翼型升力系数的影响及排序。计算结果表明,相对曲率f/l对升力系数CY的影响最大,叶轮径向间隙s影响最小,其余参数介于二者之间。更多还原

【Abstract】 The test data between impeller lift coefficient CYand radial radio r/rK,relative camber f/l, relative chord length l/t,foil setting angleβ,blade angle of attackαand impeller radial interspace s are researched,the analyzed method of multiple regression used,ordering result of these influence parameters of foil lift coefficient in axial flow pump obtained after a lot of calculation.The result shows that relative camber f/l has the largest influence on the lift coefficient CY,and the smallest influence on radial interspace s,other parameters are between them successively.更多还原
