考虑到不同湍流模型和边界层网格对风力机翼型气动性能有着不同的影响,采用4种边界层网格和4种湍流模型,对DU93-W-210翼型的气动性能进行数值计算,将计算结果与实验值进行比较.研究结果表明:在合适的边界层网格下,DES模型的计算结果最接近实验值,而且该模型对翼型尾流中的旋涡有很强的捕捉能力.
Taking into account of the effect of different turbulence modes,and mesh division in boundary layer on the aerodynamic characteristics of the airfoils for wind turbine,4 boundary layers,4 modes were employed for numeric evaluation of aerodynamic characteristics of wind turbine airfoils DU93-W-210.The calculation results were compared with experimental ones.It was shown by the investigation result that the result of calculation with DES mode was the closest to the experimental one for an appropriate boundary layer grid,and it has a strong ability to capture the vortex in the wake behind the airfoil.
