摘要 以NREL PhaseⅥ叶片为对象,基于RANS方法开展CFD数值模拟研究,发展了先在二维翼型上校正湍流模型封闭常数然后用于三维旋转叶片数值模拟的方法。将在S809翼型上校正出的SST湍流模型封闭常数β*的最佳数值用于NREL PhaseⅥ叶片的数值模拟,可显著提高该叶片在失速状态下气动力的数值模拟准确程度。 Numerical simulations were performed based on RANS method for NREL Phase VI rotor, concerning to the turbulence simulation which plays a key role in predicting aerodynamic force on blades in stall. The rotor＇ s aerodynamic performance is predicted much more exactly as using the optimal value of a closure constant β of SST turbulence model obtained in S809 airfoil simulations. It makes a possibility to improve simulations for wind turbines in complex wind circumstance by first calibrating the closure constant value in airfoil simulations and then using the calibrated value in blade simulations.
