摘要

发展了一种将小生境遗传算法与RANS方程数值求解相结合的平面叶栅全局优化设计方法.该方法针对遗传算法的搜索原理和平面叶栅的气动外形特点

提出了与之相适应的Bezier曲线参数化表达

构造了用于优化设计的适应度函数.优化设计变量是平面叶栅的参数化Bezier曲线特征多边形控制点坐标

目标函数为极大化叶栅的升阻比

约束条件综合考虑了叶栅的进出口几何安装角及叶片强度和性能等要求

约束条件的处理采用松紧罚函数法.优化得到的叶栅升阻比比初始叶栅提高了8.3%.

Abstract

A global optimization method for cascade blade based on Niche GAs(Niche genetic algorithms) coupled with RANS(Reynolds-Averaged Navier-Stokes) equation has been presented.In order to meet the search theory of GAs and the aerodynamic performances of cascade blade

Bezier curve is adopted to parameterize the cascade blade profile in this method

and a fitness function pertaining to optimization is designed.The design variables are the control points' ordinates of Bezier curve representing the cascade blade profile;the object function is the maximum lift-drag ratio of the cascade;the constraint conditions take account of the leading and trailing edge metal angle

and the strength and aerodynamic performers of cascade blade;and the treatment method of the constraint conditions is the flexible penalty function.The lift-drag ratio of optimized cascade is 8.3 percent higher than that of the initial one.
