This thesis takes the horizontal axis wind turbine's vane Reduced-Scale Model as research object,based on CFD method and the structured meshes,applying Three-dimensional turbulence numerical simulation for the wind turbine's aerodynamic characteristics.Firstly,studying the wind turbine blade surface's flowing property and the aerodynamic characteristics under the regulation of wind speed's changes,analyzing S-A turbulence model、RNG k-ε turbulence model and SST k-ω turbulence model's predictive ability on the wind turbine's aerodynamic characteristics.Afterwards,studying incoming flow turbulent intensity's influencing rule on the horizontal axis wind turbine's aerodynamic characteristics,compared to the different turbulent intensity's effect on the wind turbine's aerodynamic characteristics,and analyzing the sensibility on different wind speeds.
