Study on Aerodynamic Performance of Wind Turbine Airfoil Synthesized by Mean Camber Line Superposition Thickness between Bionic and Traditional Airfoil Bionic and Traditional Airfoil

风力机仿生与传统翼型中弧线叠加厚度合成翼型的气动性能研究

The aerodynamic performance of wind turbine needs to be improved day by day.In this paper,the bionic airfoil of wind turbine and the traditional airfoil are combined to optimize the aerodynamic performance.The new airfoil is synthesized by the method of the mean camber line superposition thickness synthesis.The flow field characteristics of 4 synthetic airfoils were calculated by using the numerical simulation of CFD commercial software Fluent,and compared with 3 original airfoils,new airfoils of different shapes were obtained,and an incomplete synthetic parameterization method for airfoils optimization was proved,which has certain engineering practical value.
