摘要
对NREL第6期水平轴风力机在风速13 m/s情况下,采用定常k-ωSST和非定常k-ωSST以及分离流DES 3种湍流模型进行了三维旋转流场数值模拟,计算结果与NASA非稳定气动力学风洞试验结果进行了对比分析,计算结果表明定常k-ωSST和非定常k-ωSST湍流模型可以很好地描述流场流动情况,非定常k-ωSST湍流模型计算结果比分离流DES湍流模型计算结果与试验结果更接近.采用非定常k-ωSST湍流模型可以满足流场计算要求.
A series of numerical simulations of the rotating NREL phase VI wind turbine flow field with the steady and unsteady k-ω SST model and detached eddy viscosity model DES at wind speed of 13m/s have been performed.The calculations are compared with the measurement results of the unsteady aerodynamic experiment in the NASA Ames wind tunnel.From the results the best performance is obtained with the steady and unsteady k-ω SST model,and the predictions with the unsteady k-ω SST model are better than the detached...
