摘　　要：为研究涡流发生器对风力机翼型DU93-W-210气动性能的影响,在有、无涡流发生器的情况下进行风洞实验。实验研究不同高度(4、6、8 mm)、不同安装角(16°、26°、36°)三角形涡流发生器的增升减阻效果。研究表明3种不同高度、安装角的涡流发生器均能使最大升力系数大幅提高,失速攻角推迟;失速前涡流发生器高度越大阻力越大,失速后3种高度涡流发生器均能大幅降低阻力。安装角越小线性段阻力越小,失速后使升阻比提高越多。To analyze the effect of vortex generator （VG） on the aerodynamic performance of dedicated wind turbine airfoil DU93-W-210, wind tunnel experiments of DU93-W-210 airfoil equipped with and without vortex generators were conducted. The effects of triangle vortex generators with different heights （4, 6 and 8 mm） and different installation angles （16° , 26° and 36° ）on lift enhancement-drag reduction were compared. The results show that vortex generators with different heights and installation angles can significantly increase the maximum lift coefficients and postpone the stall attack angles. The drag coefficients are larger with larger VGs heights before stall, and VGs with three heights can decrease significantly drag after stall. Vortex generator with smaller installation angle can gain smaller drag coefficient and larger lift-drag ratio.
