本文介绍了一种处理涡轮机尾流的气动模型。为了精确处理近尾流的尾流演化，沿着与局部流特征的相互作用，选择了一种数值扩散较低的模型，即涡粒子法，该方法本身也允许处理剪切效应和粘性扩散。利用升力线模型便于处理叶片载荷。提供了叶片尾流中分布和脱落涡流元素的正确规范的详细信息。通过在多级框架内实现该模型，降低了计算成本。此外，该模型已经高度并行化，因此可以在几秒钟的量级上实现相对快速的高保真模拟。通过与MEXICO试验转子的比较，证明了该模型产生与CFD相当精度的结果的能力。
The current paper describes an aerodynamic model for treatment of wind turbine wakes. For accurate treatment of the wake evolution for the near wake, along with interaction with local flow features, a model with low numerical diffusion has been chosen, a vortex particle method, which inherently allows treatment also of shearing effects and viscous diffusion. Treatment of blade loading is facilitated with the use of a lifting-line model. Details of correct specification of distributed and shed vortical elements in the blade wake are provided. Reduction of the computation cost has been achieved by implementing the model within a multilevel framework. In addition the model has been highly parallelised, so that relatively quick simulations at high fidelity can be achieved on the order of seconds. The ability of the model to produce results of comparable accuracy to CFD is demonstrated by comparison to the MEXICO test rotor.
