Abstract
Numerical investigation of large thick and low Reynolds airfoil of wind turbines by mounting Gurney flaps was carried out. The influenced rules of the height of Gurney flaps on the aerodynamic performance of airfoil under different height of flaps were achieved, and the optimal height of Gurney flap was presented. At last, the mechanism of wind turbine performance controlled by Gurney flap was discussed. The results can provide the theoretical guidance and technical support to wind turbines control in practical engineering.
