| 摘 要： | 对S823翼型及其对应的带有Gumey襟翼的翼型进行了数值计算,针对风力发电机运行环境,研究Gumey襟翼对S823翼型气动性能的影响.计算结果表明:带有Gumey襟翼的翼型明显改善了翼型压力面和吸力面的压力分布,因此翼型升力及升阻比均比翼型原型有显著增加.

| Abstract: | In this paper, the numerical simulation for S823 aerofoil and the corresponding aerofoil with Gurney flap is carried out.According to the operating environment of wind turbine generator, the influence of Gurney flap on aerodynamic characteristic of S823 aerofoil is researched.The calculation result shows that the aerofoil with Gurney flap has obviously improved the pressure distribution of pressure surface and suction surface.Therefore, the aerofoil lift force and lift-drag ratio are notably improved compar... |
