摘要	Taking the wind rotor of a 33 kW two- bladed horizontal- axis wind turbine and the NREL Phase VI wind turbine blade as the research object,the distribution law of surface pressure coefficient of NREL Phase VI wind turbine blade under uniform flow condition was obtained through numerical simulation,the result was compared with the experimental value to verify the validity of the numerical calculation method. Based on this,the effects of different wind shear flow on the surface pressure of the wind turbine blade and the variation law of the surface pressure of the blade with the azimuth angle under wind shear were studied. The results show that when the wind shear exponent increases from 0.3 to 0.5,the surface pressure of blade has different changes under different azimuth angle; In the shear inflow,in the area where the pressure surface and the suction surface of the blade do not separate,the pressure exhibits a positive cosine variation with the azimuth angle,the closer to the trailing edge,the smaller the pressure fluctuation is. At suction surface pressure minimum position,the pressure fluctuation with azimuth angle is the largest. In the region where flow separation occurs on the suction surface of the blade,the pressure fluctuation with the azimuth angle is unstable; No matter the pressure surface or suction surface,there is phase lag phenomenon in the pressure change with the azimuth angle. The closer to the blade root,the more obvious the hysteresis phenomenon is. © 2018, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
