摘要
基于计算流体力学方法(CFD),通过求解URANS方程与SST湍流模型,对Tj?reborg 2 MW风力机风轮在偏航角0°、10°、30°工况下的气动特性进行计算,结果表明数值计算的功率与实验值吻合较好。分析不同偏航角下风轮的功率、推力、叶片各截面切向力、法向力载荷和压力分布的变化规律。偏航工况下一个旋转周期内风轮功率、推力呈现3P波动性质,叶片气动载荷沿旋转方向呈现正弦交变性质,最大载荷发生在方位角90°附近区域。
The aerodynamic characteristics of the Tjaereborg 2 MW wind turbine rotor were researched under yaw angles of 0°,10°,30° based on computational fluid dynamics method(CFD)by solving the URANS equations with the SST turbulence model. Numerical results of power agree well with the experimental values. Under yaw conditions,wind wheel power and thrust behave 3 P properties in one rotational period. The azimuthal variation of aerodynamic loads is characterized by alternating properties of approximate sine curve with the maximum value occurred in region near azimuth angle of 90°.
