研究了装有涡流发生器的风力涡轮机翼型的绕流问题。从三个不同的雷诺平均Navier Stokes（RANS）求解器与两种不同的湍流模型和两种不同的VG建模方法的预测进行比较，他们之间的实验数据。最好的结果是获得更昂贵的完全解决VG的方法。如果网格相关的数值扩散被最小化，并且只考虑力系数极，则成本有效的BAY模型也可以提供可接受的结果。
The flow around a wind turbine airfoil equipped with Vortex Generators (VGs) is examined. Predictions from three different Reynolds Averaged Navier Stokes (RANS) solvers with two different turbulence models and two different VG modelling approaches are compared between them and with experimental data. The best results are obtained with the more expensive fully resolved VG approach. The cost efficient BAY model can also provide acceptable results, if grid related numerical diffusion is minimized and only force coefficient polars are considered.
