摘　　要：为研究格尼襟翼对风力机专用翼型DU93-W-210气动性能的影响,在有/无格尼襟翼情况下进行风洞实验(雷诺数为1×10~6)。实验研究高度为1.5%C、2.0%C、2.5%C格尼襟翼增升效果。研究表明:格尼襟翼能有效提高翼型的升力系数,襟翼高度越高,升力系数越大,相应的阻力系数也有所增大。格尼襟翼在中、高升力系数情况下效果较好;高度为1.5%C的格尼襟翼可获得较大升阻比。为了进一步减少阻力,对平板格尼襟翼开30°、45°、60°锯齿。结果表明,平板襟翼开锯齿能减小阻力;30°锯齿襟翼能在较大范围内增大升阻比,增升效果最佳。To analyze the effect of Gurney flap on the aerodynamics performance of dedicated wind turbine airfoil, wind tunnel experiments were conducted with DU 93-W-210 airfoil equipped with and without Gurney Flap. Ttle Reynolds number in the test was 1×10^6. The effects of Gurney Flap with different heights （1.5%, 2.0% and 2.5% chord height） on lift enhancement were compared. The results showed that Gurney flap with different height could significantly increase the lift coefficients, while the drag coefficients were also a little increased. The Gurney flap showed that good performance on the lift enhancement at moderate to high lift coefficient conditions. Compared with other height Gurney, the 1.5%C height Gurney flap showes the best performance. In order to decrease the drag coefficient, the Gurney flaps were serrated with different angles （30°, 45° and 60° ）. The results showed that the serrated Gurney flap could decrease the drag coefficients. The serrated Gurney flap with 30° angle showes the best performance, which could widely increase the ratio of lift to drag of the airfoil.
