摘要
基于翼型型线和噪声预测理论,提出以风力机设计运行攻角范围内平均效噪比为设计目标来指导翼型设计的新方法,并建立翼型的优化设计模型。选取相对厚度为21%的翼型进行了优化计算分析,得到了低噪声及高气动特性优化翼型的形状,通过与风力机专用翼型DU93-W-210和FFA-W3-211的性能比较以及风洞试验测试,很好的验证了该优化方法的通用性及实用性。
Based on design theory of airfoil profiles and airfoil self-noise prediction model, a new method with the target of the airfoil average efficiency-noise ratio of design ranges for angle of attack had been developed for designing wind turbine airfoils. The airfoil design method was optimized for a relative thickness of 21% and a new airfoil was obtained. To illustrate the optimization method, the aerodynamic characteristics and noise of the optimized airfoil were calculated and analyzed. Through performance comparison of a DU93-W-210 airfoil and a FFA-W3-211 airfoil which are widely used in wind turbine constructing blades, and wind tunnel test, the practicability and commonality of the optimization method were verified.
