6) jet wake model
射流-尾迹模型
1.
Based on a 3 D flow analysis with the jet wake model and performance prediction, an optimization model for the centrifugal pump blade profile is developed with the efficiency as the objective function and the incident angle and distribution factor of the blade angle as design variables.
在采用射流－尾迹模型进行三维流动分析和性能预测的基础上，建立了以效率为目标函数，以进口冲角和叶片安放角分布系数等参数为设计变量的离心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
补充资料：飞机尾迹
[[飞机尾迹]]：飞机飞行中发动机排出的废气与周围空气混合凝结而成的特殊的云。一般发生在气温低于-40度、又有适当湿度条件的空气层中。飞机尾迹对飞行没有影响，但暴露行踪，对航空兵战斗行动有一定的影响。
