Abstract: 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 S?rense’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 S?rensen’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.
