【Abstract】 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.更多还原
