摘要(Abstract):

介绍了一种混流泵叶轮叶片的设计方法———准三元设计法。该方法是以速度矩Vur为控制变量,通过正反问题迭代计算,从而构制出叶片,力求使叶轮叶片形状与叶轮内实际流态相吻合,从而得到性能优异的混流泵。
A quasi 3-D design method for mixed-flow pump was introduced.The method uses the velocity moment of fluid as the command variable and through interating computation of positive and inverse question to construce the blade.And in this method we must inosculate the blade shape with the real status of the flow field in the impeller,thus a good performance mixed-flow pump can be designed.
