摘要

采用k-ω SST湍流模型和γ-Re_θ转捩模型计算带有涡流发生器翼型的气动性能参数,基于湍流状态下的叶片翼型攻角变化,分析出叶片在准稳态阵风工况下气动攻角变化规律,研究涡流发生器在不同湍流强度、空气密度条件下对风电机组叶片实际运行功率和载荷特性变化的影响。结果表明,风电机组叶片极易受空气密度、环境湍流、转速变化、阵风突变等影响使得翼型易发生失速,涡流发生器可降低风电机组叶片对空气密度和湍流强度影响的敏感性,降低叶片摆振方向载荷和振动。

Abstract

The transition γ-Re_θ and k-ω SST turbulence model were used to calculate aerodynamic characteristics of the airfoil with vortex generators, based on the variation of the blade airfoil angle of attack under the turbulent condition, the aerodynamic angle of attack variation pattern of the blade under quasi-steady gust conditions was analyzed, the actual power and load characteristics of wind turbine with vortex generators were investigated in different turbulence and air density conditions. The results indicate that the airfoil stall characteristic of wind turbine blades can be affected by air density, ambient turbulence and rotor speed. Vortex generators an reduce the sensitivity of air density and turbulence intensity to wind turbine blades, as well as decrease blade load and vibration in edgewise direction.
