摘要
在大厚度、低雷诺数风力机专用翼型上加装缩进式Gurney襟翼进行数值模拟研究,获得了Gurney襟翼在相同的襟翼高度下,不同的襟翼位置对风力机专用翼型气动特性的影响规律,给出最佳襟翼位置;最后探讨了缩进式Gurney襟翼控制流动的机理.所得结果可为实际工程风力机的控制提供理论指导和技术支撑.
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.
