摘要 研究了NACA0012翼型在低Reynolds数不同湍流度下的空气动力学特性.既运用了有限谱法和QUICK格式相结合的数值计算方法,又通过实验手段,研究了湍流度对流场的影响,并得到了计算与实验相符的结果.计算结果说明了有限谱法的高精度及与其他格式结合后应用的灵活性.对翼型受力和流场的结果分析显示:低湍流度下无明显的失速特征,高湍流度下失速特征明显;湍流度还对边界层后的剪切层有很大影响,高湍流度的受力特征和流场结果与高Reynolds数下的情形相似. Effect of the turbulence intensity of the oncoming stream on the aerodynamic characteristics of NACA-0012 airfoil was investigated by a direct numerical simulation.The numerical results were found to be consistent with the experimental measurements.Based on the finite spectral QUICK scheme,the simulation gets the high accuracy results.Both the simulation and experiment reveal that the airfoil stall does not exist for low turbulence intensity,however,occurs when the turbulence intensity increases sufficiently.Besides,the turbulence intensity has a significant effect on both the airfoil boundary layer and the separated shear layer.
