摘　　要：通过悬浮流的物理模型建立、通道几何结构及流动参数优化、悬浮流的耦合计算等,提出四项设计准则:叶片前1/3长度上取较大的曲率半径;控制流道中间段有效通道的当量扩张角;取较大的叶片包角;控制叶片出口角。Four designing criterions were put forward through the establishment of physical model of suspension fluid,the optimization on geometry structure and flow parameter in the channel and the coupling calculation of the suspension fluid,which include selecting the bigger radius of curvature in the former one-third length of the blade;controlling the equivalent divergence angle of the effective channel in the middlesection;selecting bigger angle of blade and controlling blade outlet angle.
