Numerical Simulation of Aerodynamic Performance of Small Vertical Axis Wind Turbine

风机翼型作为叶片外形设计的根本,对叶片的空气动力特性、质量以及整个风机捕获风能的能力有着重要的影响。利用FLUENT流体仿真软件对翼型进行数值模拟,使用RNG k-ε和SST k-ω湍流模型模拟得到翼型随攻角变化的升阻力系数曲线,并与试验数据进行对比,得出SST k-ω湍流模型更为准确。对风机叶片翼型进行气动数值模拟计算和分析,有助于深入了解翼型的气动性能,为风机翼型的气动特性研究提供理论基础。

Wind turbine airfoil as a basis for leaf shape design has an important influence for aerodynamic characteristics and qualities of the blades and fan＇s ability to catch the wind. This paper used fluent fluid simulation software for numerical simulation of airfoil and used the RNG k-ε and SST k-ω turbulence model and simulation system with attack angle change curve testing airfoil attack angle,airfoil lift,drag coefficients. And turbulence model is more accurate through comparing with experimental data.It is contribute to learn more about airfoil aerodynamic performance and provide theoretical basis for research on wind turbine airfoil aerodynamic performance through numerical simulation of wind turbine blade airfoil aerodynamic calculation and analysis.
