| Abstract: | The numerical Simulation of large thick and low Reynolds airfoil of wind turbines equipped with Gurney flaps was carried out.The influenced rules of the position of Gurney flaps on the aerodynamic performance of airfoil under different positions of flaps were achieved,and the optimal location of Gurney flap was presented.At last,the mechanism of wind turbine performance controlled by Gurney flap was discussed.The results could provide the theoretical guidance and technical supports for wind turbine control in practical engineering. |
