Gurney襟翼对风力机专用翼型气动性能的影响
Effect of Gurney Flap on Aerodynamic Performances of Special Airfoil for Wind Turbine
摘要
Abstract
In order to determine the effects of Gurney flaps on dedicated airfoil of wind turbine,DU95-W-180 airfoil with Gurney flaps was calculated numerically by solving the N-S equations,the height of flaps were 1% ,2% ,3% ,4% of the airfoil chord respectively and the angle of attack varied from -8° ~ 18° ,the aerodynamic performance of airfoils of various working conditions were calculated and compared with that of original airfoil.the comparison shows that Gurney flap has good performance for dedicated airfoil wind turbine, and the performance is closely related with the height of the flap, and the higher the flaps, the larger the lift coefficient and the corresponding friction coefficient.The Gurney flap should be employed at moderate-to high lift coefficient conditions, while not advisable at low-to-moderate life coefficient conditions.关键词
