射流参数对风力机叶片气动性能的影响
Effect of Jet Parameters on the Aerodynamic Performance for the Wind Turbine Blade
摘要
Abstract
At the high angles of attack,there is a serious flow separation phenomenon for the wind turbine blade,with reducing the power generation efficiency of wind turbines.The impact was studied on the wind turbine blade performance with slotted position and jet angle changed,using computational fluid dynamics.The results show:The effect of jet positional could be remarkable,and occupy an important position.With slotted position moved,the lift coefficient decreased.When the position did not exceed X = 0.7,the jet can weaken the influence of recirculation zone.The increase of lift coefficient was limited with jet angle in harsh flow filed.When the jet angle was 2 degree,its performance was better.Jet can sweep low energy fluid in the boundary layer, Strongly weaken large-scale vortex structure and trailing edge eddypowerfully improve the design of wind turbine blades.关键词
