| 摘 要： | 以某风力机翼型为研究对象,选择其设计点升阻比作为优化目标,采用基于均匀设计的响应面法对其进行气动优化设计。首先用B样条曲线对该翼型拟合并求其控制点,然后利用均匀试验设计方法建立计算试验样本点分布表并进行各样本点的CFD计算,最后建立响应面模型,进行优化设计,使设计点升阻比提高12.13%,而且在所有攻角下升力和升阻比都有所提高。算例表明,本文进行风力机翼型优化的方法节省时间,优化效果明显。

| Abstract: | The optimization method of the wind turbine airfoil presented in this paper is based on the combination of response surface method(RSM) and uniform experimental design.A wind turbine airfoil is taken as an example to optimize its maximum lift-drag ration at design point.First the contour of the airfoil is fitted by B-spline curves.After the control points have been obtained,the distribution of the sample points is appointed by the uniform experimental design method and the flow fields of the airfoil at corr... |
