摘　　要：以NH1500叶片为基本布局,在其尾缘加装高度为当地弦长4%的Gurney襟翼。采用计算流体力学方法,分析在多种工况下Gurney襟翼对水平轴风力机整机叶片的气动性能控制效果,并与原型叶片的气动性能实验值进行对比。在此基础上探讨Gurney襟翼的增升机理。计算结果表明,本文中所使用的改型叶片相比基本型叶片,功率得到显著提高。In this paper,a numerical simulation based on the NH1500 blade equipped with Gurney flap is presented.The height of the Gurney flap is 4percent of the local chord length of the blade.Analysis influence of Gurney flap under different wind speed by CFD and Comparison with experimental prototype aerodynamic performance of the NH1500 blade.The mechanism of the Gurney flap on wind turbine blade is also discussed in this paper.The result shows that,equipping of Gurney flap increase the efficiency of the wind turbine.
