基于遗传算法的变桨型风力机翼型设计
Optimization Design of Airfoils for Variable-Pitch Wind Turbines Based on Genetic Algorithms
摘要
Abstract
The design requirements of wind turbine airfoils is analyzed in terms of the aerodynamic effi-ciency and the load output. The blade gross performance is directly set as the design objective for aero-foil optimization, and genetic algorithm is used in the design procedure. Computational fluid dynamics (CFD) and the software XFOIL are used to calculate the airfoil aerodynamic characteristics. Finally, a four-airfoil family for pitch-regulated wind turbines is designed with thicknesses ranging from 18% to 30%. The result shows that the designed airfoils have higher lift-to-drag ratios in the efficiency con-trolled area below the rated wind speed and a relatively low lift coefficient in the load controlled area above the rated wind speed. Therefore, the airfoils can comprehensively improve the wind turbine aero-dynamic performance.关键词
