Hybrid Vortex Method for the Aerodynamic Analysis of Wind Turbine

Abstract EN

The hybrid vortex method, in which vortex panel method is combined with the viscous-vortex particle method (HPVP), was established to model the wind turbine aerodynamic and relevant numerical procedure program was developed to solve flow equations.

The panel method was used to calculate the blade surface vortex sheets and the vortex particle method was employed to simulate the blade wake vortices.

As a result of numerical calculations on the flow over a wind turbine, the HPVP method shows significant advantages in accuracy and less computation resource consuming.

The validation of the aerodynamic parameters against Phase VI wind turbine experimental data is performed, which shows reasonable agreement.
