Numerical Simulation of the Flow Control Using Gurney Flaps for a Wind Turbine

This paper presents a numerical simulation study on the large thick and low-Reynolds airfoil of wind turbine equipped with Gurney flaps.The influenced rules of the height of Gurney flaps on the aerodynamic performance of airfoil under different height of flaps are obtained,and the optimal height of Gurney flap presented.At last,the mechanism of wind turbine performance controlled by Gurney flap is discussed.The results can provide the theoretical guidance and technical support to wind turbines control in the engineering practice.
