To accurately and rapidly predict the aerodynamic performance of large wind turbine wheel

a hybrid panel viscous-vortex particle (HPVP) method was established to calculate the wind turbine aerodynamic performance

and corresponding calculational program was developed

the model experiments in controlled conditions (MEXICO) wheel was chosen to validate the accuracy and reliability of HPVP method by comparison of calculational result

test data and CFD method. The results show that the pressure distribution of the main working zone of blade is predicted accurately in HPVP method. Compared with CFD method

when the flow separation is small

the aerodynamic calculation in HPVP method is faster than that of CFD method

and the calculational time by HPVP method is one thousandth of CFD method. Additionally

some other flow details of flow field of the wind turbine wheel can be also showed by HPVP method including the pressure distribution of blade.
