Numerical simulation on aerodynamic performance of airfoils for the wind turbine in different curvature

Zhonghe Han

Abstract

The analysis of the aerodynamic performance of wind turbine airfoil is an important foundation of the wind turbine aerodynamic design and optimum operation.In this paper,the simulation for the aerodynamic performance of the airfoil NACA4412 was done by using NUMECA software.The aerodynamic performance of the airfoil NACA4412 at attack angle 8°and 14°was analyzed.The results were accordant with the experimental data.Finally,the aerodynamic performance of three airfoil NACA2412,NACA4412 and NACA6412 with different camber were analyzed.And supply some suggestions for choosing airfoil camber and designing airfoils.
