| 摘 要： | 本文在应用二维Euler方程及边界层方程相结合的跨音速粘流的计算方法基础上,以叶栅损失和做功能力为目标函数,采用无量纲化的多目标最小偏差法构造统一函数,然后采用可变容差法进行优化求得较为满意的解,从而形成了一种带有多混合变量、多约束以及多目标的跨音速叶栅优化设计方法。

| Abstract: | This paper presents a multiobjective optimization design method for transonic cascades with mixed variables and constraints.On the basis of the computation method of two-dimensional Euler equations coupled with boundary equations for transonic viscous flow,the cascade aerodynamic losses and work potential are considered as the two objective functions,and a united objective function is formulated using dimensionless minimum-deviation method,by which the two-objective optimization problem is divided into two single-objective optimization problems.Then,the efficient optimal solution is obtained with the optimization algorithm of flexible tolerance method. |
