使用基于速度面元法的势流数值模拟方法，以NREL Phase VI为例进行了叶片气动载荷和风轮近尾流场的数值模拟。将势流数值模拟、叶素动量理论和计算流体力学CFD方法的计算结果与实验数据进行了对比分析。结果表明使用速度面元法计算风轮绕流场具有较高的计算精度和求解效率，为大规模风力机群的流场计算和出力预报提供支撑。
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.
