中文摘要：
采用γ-Reθt转捩和SST湍流模型,从来流风速7、10、13、15、20和25m/s六个工况,分别模拟计算Phase VI风轮的转矩、叶片表面压力系数以及表面流线,并与S？rensen计算结果、风洞试验数据进行对比。转矩对比结果表明,转捩模型计算结果与试验值吻合良好,最大误差为7.8%;SST湍流模型最大误差为24.3%;Sorensen计算最大误差为33.4%,误差主要发生在叶片失速风速区域。在大部分叶片截面,转捩模型的表面压力系数结果与试验值更加吻合。从叶片表面流线看出,转捩模型可以反映出叶片表面转捩现象,而湍流模型无法体现。
英文摘要：
γ-Reθt transition and SST turbulence models were used to simulate the wind turbine named Phase VI from six wind speeds, 7, 10, 13, 15, 20 and 25m/s. Their simulation results of rotation torque, pressure coefficient of blade surface and stream lines of surface, were compared with experimental results of wind tunnel and Sorense＇s computation data. The comparison of torque shows that the results of transition model has better agreement with experimental ones and its maximum error is only 7.8%; the maximum error of SST model is 24.3%, while the maximum error of Sorensen＇s results reaches 33.4%, which main occurs in range of the wind speed with stall happening. In most cross-sections of different positions, pressure coefficients of transition model have better agreement with experimental results. From the streamlines of blade surface, it can be seen that the transition model results can reflect the transition phenomenon, while the SST turbulence model cannot.
