Performance Prediction of a Horizontal Axial Wind Turbine Based on Wind Velocity Correction Produced by the Complicated Wake Vortexes

The method to predict the performance of a horizontal axial wind turbine (HAWT) based on wind velocity correction produced by the complicated wake vortexes is mainly introduced and described, which adopts alterable circulation along the wind rotor blade axis and combines the aerodynamic features of a horizontal axial wind turbine to evaluate its aerodynamic performance. A computational example shows that the method, suggested and discussed in the paper, has good feasibility and reliability in predicting aerodynamic performance of a HAWT.
