摘　　要：为研究风力机翼型覆冰形态及其失速特性,采用覆冰软件FENSAP计算风力机翼型的雾凇、雨凇覆冰形态。使用Fluent流体仿真软件计算覆冰前后空气流场,翼型升力系数、阻力系数。研究结果表明,风力机翼型雾凇覆冰呈规则流线形,雨凇覆冰呈角状冰。覆冰后,翼型空气动力特性发生较大变化,其升力系数减小,阻力系数增大,失速攻角减小。雨凇加剧破坏翼型气动外形,对翼型升阻特性的影响最严重。In order to research the ice form of wind turbine airfoil and its stalling characteristics, the rime and glaze ice forms of wind turbine airfoil were calculated by using the Ice software FENSAP, and the air flow field, the airfoil lift coefficient and the resistance coefficient were calculated by using the fluid simulation software Fluent. The research results indicate that the rime ice for the wind turbine airfoil presents regular streamline form, and the glaze ice is an angular ice. The aerodynamic performance of the airfoil has been changed after covering the ice, the lift coefficient decreases, the resistance coefficient increases and the stall angle decreases. The glaze ice contributes the destruction of the airfoil aerodynamic configuration, and the influence of glaze ice on the lift-drag performance for airfoil is the most serious.
