摘要

为探究湍流工况下涡流发生器流动控制的效果，基于风洞试验平台，在雷诺数

= 1.5 × 10

、不同来流湍流强度（0.50%～10.18%）条件下，研究了涡流发生器对DU93-W-210风力机翼型气动特性的影响规律。通过对比分析静态和动态表面压力系数、升阻力系数及流动分离特性，发现：涡流发生器能够有效延迟翼型表面流动分离，随着来流湍流强度的增大，静态气动性能改善的攻角范围从11°～17°扩大到11°～ 20°，最大升力系数的增幅先增大后减小（湍流强度0.50%、6.35%、10.18%下相对增幅分别为5.45%、7.79%和6.91%）；但在深度失速时，涡流发生器无法抑制分离，压差阻力系数增大。动态试验表明，湍流强度的增加使涡流发生器在下俯阶段能于更大攻角范围内提升升力，且下俯阶段的气动改善效果显著优于上仰阶段。翼面粘贴丝线的流动可视化方法进一步验证了上述结论，本文研究可为湍流工况下风力机翼型的优化设计提供指导。

Abstract

This study investigates the effects of vortex generators (VGs) on the aerodynamic performance of a wind turbine airfoil under turbulent inflow conditions. A wind tunnel test setup was established to examine the flow control effects of VGs on the DU93-W-210 airfoil at various turbulence intensities with a Reynolds number of 1.5×10

. The pressure coefficients

lift and drag coefficients

and flow separation were measured for static and dynamic conditions. Results showed that when the inflow turbule

nce intensity increased from 0.50% to 10.18%

VGs effectively delayed flow separation on the airfoil surface

expanding the range of angles of attack for enhanced static aerodynamic performance from 11°–17° to 11°–20°. The maximum lift coefficient increase initially rose and then decreased with higher turbulence intensity (the relative increments under the three conditions were 5.45%

7.79%

and 6.91%). During deep stall

VGs failed to suppress separation

resulting in increased pressure drag coefficients. Dynamic tests revealed that increased turbulence intensity allowed VGs to enhance lift at wider angles of attack during the downstroke phase. The‌ aerodynamic improvement ‌during downstroke‌ was ‌significantly greater than‌ during ‌the‌ upstroke phase. Flow visualization using tuft methods further validated these findings. This research provides ‌practical‌ guidance for optimizing wind turbine airfoil design ‌in‌ turbulent conditions.
