新规划的以及现有的风力涡轮机的空气动力学性能可以通过消除失速来提高。涡流发生器(VG)可以有效延迟风力涡轮机叶片内侧部分发生的空气分离。许多学者研究了VG在流量控制方面的原理,并验证了其提高效率的能力。本文对已在风力涡轮机领域进行测试的最先进的 VG 进行了全面回顾。首先阐述了与 VG 相关的流动控制的基本原理,然后回顾了先前关于几何参数对 VG 行为的影响、VG 对风力涡轮机专用翼型的影响以及参数化 VG 模型的研究。本文还讨论了影响风力涡轮机叶片上 VG 行为的空气动力学因素。提出了未来的研究方向。
The aerodynamic performance of newly planned as well as existing wind turbines can be improved by eliminating stall. Vortex generators (VGs) can effectively delay air separation occurring on the inboard-section of the wind turbine blade. Many scholars have investigated the principle of VGs in terms of flow control and validated their ability to enhance efficiency. This paper provides a comprehensive review of state-of-the-art VGs that have been tested in the wind turbine field. The basic principle of VG-related flow control is first illustrated, followed by reviews of previous studies regarding the effects of geometric parameters on VG behavior, the effects of VGs on dedicated airfoils for wind turbines, and parametric VG models. The paper also discusses aerodynamic factors impacting the behavior of VGs on wind turbine blades. Future research directions are proposed.
