【Abstract】 By taking the minimum hydraulic losses of double cascades as the objectivefunction, the profile of stationary vanes and guide vanes and their relativecircumferential positions are optimized. The optimization results show that the design method can raise the hydraulic efficiency of the diversion components compared with the traditional design methods.更多还原
