Numerical investigation on the flow control of FFA-W3 airfoil with gurney flaps

摘要

Numerical investigation on large thickness and low Reynolds airfoil of wind turbines by mounting Gurney flaps was carried out. The influenced rules of the position of Gurney flaps on the aerodynamic performance of airfoil the under same height of flaps were achieved, and the optimal position 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.
