Numerical Simulation and Study on Three-Dimensional Flow Field of Wind Turbine Impeller

Abstract:

hree-dimensional aerodynamic performance of wind turbine impeller is one of the most important elements in the wind turbine design process; its accuracy directly impacts the efficiency and stability of wind turbine operation. As the current numerical simulation for three-dimensional aerodynamic performance of wind turbine impeller does not fully consider the impact of the rotation effect of the wind turbine and other factors, a relatively large calculation error can be resulted. In this paper, a 1.65MW Vestas wind turbine was taken as an model, and design process of wind turbine blade was made. Also, three-dimensional numerical simulation was made to get a comprehensive dynamic performance of the wind turbine, and the influence of wind turbine power and wind farm efficiency by the pitch angle and wind speed were made.
