摘要
本文介绍了混流泵叶轮叶片一种准三元设计法。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。
This paper introduces a quasi 3-D design method for the blade of the impeller of the mixed-flow pump. With velocity moment Vur as the command variable, the shape＇.of blade is developed by iterating computation of positive and inverse question, which ensures full coincidence of blade shape with real flow status through the impeller and creation of a mixed-flow pump with good performance.
