Luo Xingqi · Large Electric Machine and Hydraulic Turbine · 2002
A optimization design approach of plane cascades based on genetic algorithm is presented in this paper.The thicknessless wing bone line was designed by using singular-point distribution method,then the best thickness distribution law along the known bone line was searched through minimizing the flow loss of the cascades surface boundary layer by using genetic algorithm,the thickness distribution was parameterized.The flow field analysis of known cascades was accomplished by the computer program based on boundary element method.Apply the approach to the design of ZZ440 cascades,the result was proved to be effective and feasible.
