摘要：

A computational method based on rotor free-wake model was developed for horizontal axis wind turbine's aerodynamic performance prediction. The analytical method combined a Weissinger-L lifting surface model with a time-marching free vortex method to simulate the rotor flow field. Adams-Moulton predictor-corrector scheme was used to improve computational order of accuracy. The comparison between the calculated results of model wind turbine under axis flow condition, including tip vortex geometry and aerodynamic performance, and available experimental data shows that this method is suitable for wind turbine aerodynamic performance analysis. Finally, a series of numerical calculations were made to investigate the evolving of tip vortex geometry and aerodynamic performance of the wind turbine when yawing 30° out of the wind and pitch angle increasing from 2° to 4°, some significant conclusions were obtained. © 2011 Chinese Society for Electrical Engineering.
