英文摘要：

The aerodynamic loads and the near-wake flow fields of a wind turbine, NREL Phase VI, are simulated by numerical simulations using the velocity based panel method. The results of numerical simulations of potential flows are analyzed and compared with that of blade element momentum theory, computational fluid dynamics （CFD） and experimental data. It is shown that the velocity based panel method is more precise and efficient for the aerodynamic simulations of the wind turbine. The conclusions can be used as technical supports for the flow field calculation and the performance prediction of wind turbine groups.
