摘要

为改善大型叶片叶根部位大厚度翼型的气动性能、提升叶片发电量采用数值模拟方法研究不同高度参数的T型扰流板对两种大厚度翼型气动性能的影响。结果表明,扰流板在一定攻角范围内会改变翼型表面压力分布并增大升力系数、阻力系数以及升阻比;增加扰流板高度会使升力系数进一步提升;厚度较大的翼型安装扰流板后升力系数的提升明显大于厚度较小的翼型;在叶根部位安装扰流板会同时增加叶片的发电量和载荷。

Abstract

In order to improve the aerodynamic performance of large-thickness airfoils at the root of large blades and enhance the power generation of the blades, this study investigates the influence of T-shaped spoilers with different heights on the aerodynamic characteristics of two large-thickness airfoils using numerical simulation. The results show that within a certain range of angles of attack, the spoiler alters the pressure distribution on the airfoil surface and increases the lift coefficient, drag coefficient, and lift-to-drag ratio. As the height of the spoiler increases, the lift coefficient further increases. The increase in lift coefficient caused by the spoiler is significantly greater for the thicker airfoil compared to the thinner one. Installing a spoiler at the blade root simultaneously increases the annual energy production （AEP） and the structural load on the blade.
