风力机专用翼型综合优化设计方法
Design Methods of Comprehesive Optimization of Wind Turbine Airfoils
摘要
Abstract
The wind turbine airfoil aerodynamic and noise performace were considered as optimiza-tion design target at the same time,then a design method was established for multi operating points and targets.Parametric model of airfoil contour was constructed by using Bezier curves,and the gen-eral equtions for control points coordinate were deduced according to airfoil discrete data points.Based on semi empirical airfoil noise prediction model the dynamic performance of airfoil was calculated by using XFOIL,then the optimized airfoil was obtained by combining the genetic algorithm.Taking USA NREL wind turbine airfoil S834 as intital airfoil,weight assignment scheme was designed com-prehensively.The results show that comparing to initial airfoil the noise of optimized one is reduced and the lift drag ratios are increased under the main angle range,therefore better aerodynamics and acustic performance are abtained for new airfoil.关键词
