摘　　要：本文提出一种全三维反问题计算方法 ,将速度分解成周向平均和周期性脉动分量 ,用Fourier变换将全三维问题转化成多个二维问题求解 ,分别用涡及源汇模拟叶片骨线及叶厚的作用 ,并应用于叶片可调混流泵的转轮设计 ,计算表明该方法可以用于该类泵型的优化设计。In this paper, a full three\|dimensional inverse method for the design of mixed flow pump runner with adjustable blades is described.The three\|dimensional flow in the runner is decomposed into a tangential mean flow and a tangential periodic flow.The three\|dimensional flow is simplified to several two\|dimensional flows with the Fourier expansion.The blades are represented by superposition of vortices and sources on the blade mean surface.The new method is applied to the design of a mixed\|flow pump runner and the result is satisfied.
