摘要
在风力机大厚度、低雷诺数专用翼型上加装Gurney襟翼进行数值模拟研究。获得了Gurney襟翼在不同襟翼高度下,襟翼高度对翼型气动特性的影响规律,给出最佳襟翼高度,最后探讨Gurney对风力机性能的控制机理。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。
This paper presents a numerical simulation study on the large thick and low-Reynolds airfoil of wind turbine equipped with Gumey 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.
