中文摘要	A method was developed using blade shape approximation based on a full three-dimensional design model to solve the bidirectional flow problem of pump-turbine runners. The objective blade was designed in the turbine flow direction; while the flow field was obtained with the blade in the pump flow direction then designed. Accelerating simplex method was applied to control the values of swirl distribution variables and make the designed blade progressive to the objective blade. The bidirectional flow fields were both simulated, with the runner efficiency and cavitation estimated. The results of the design of a high-head pump-turbine runner show that the method is applicable and effective.
