在三维粘性流场分析和性能预测的基础上，建立了以效率为目标函数，以叶片的包角、出口角等参数为约束条件的混流泵叶片形状优化模型，应用数学规划的方法寻求满足一定流量和扬程要求的最佳叶片形状
Based on three-dimensional viscous flow field analysis and performance prediction, the optimization model of mixed-flow pump blade shape with efficiency as the objective function and the parameters of the blade wrap angle and exit angle as the constraint conditions is established. The mathematical programming method is used to satisfy certain The best blade shape for flow and lift requirements
