风力机叶尖涡特性及其控制
Characteristics and Control of Blade Tip Vortex of Wind Turbine
摘要
Abstract
The vortex of a wind turbine blade tip is studied, and a control device is designed by numerical simulation. Vortex diffusers with different pitch angles are installed at the blade tips to control the vor-tex. The characteristics of the blade-tip vortex and the surface pressure distributions along the blade are analyzed. Moreover, the variation of the flow characteristic of vortex in different tip speed ratios is ana-lyzed. Results show that the strength of blade-tip vortex can be reduced by the control of vortex dif-fusers.关键词
