摘要
为了研究襟翼高度对风力机气动性能的影响,对加装不同高度襟翼的Phase VI风力机进行数值模拟。分析加装高度分别为1%C、2%C、3%C、4%C、5%C和6%C(C为叶片各截面处的翼型弦长)Gurney襟翼的风力机在不同工况下的输出扭矩,说明襟翼的增升机理。结果表明:在风力机叶片上加装一定高度的Gurney襟翼能有效提升风力机的气动性能。且襟翼的增升效果随着襟翼高度的增加呈现先提升后减小的趋势。当襟翼高度达到一定值后,风力机的气动性能非但未提升,反而急剧下降。
In order to study the influence of flaps height on the wind turbine,the wind turbine aerodynamic performance at different wind speeds is numerically simulated which installed Gurney flaps with different heights.The aerodynamic performance of the Phase VI wind turbines is analyzed at different working conditions with the addition height of 1%C,2%C,3%C,4%C,5%C and 6%C Gurney flaps and illustrated the increasing principle of the flap.The results show that the Gurney flaps can effectively improve the aerodynamic performance of the wind turbine.The effect of the flap increases with the increase of the height of the flaps,and then decreases.When the height of the flaps reaches a certain value,the aerodynamic performance of the wind turbine is not only prompted,but also drastically reduced.
