风力发电需求的增加与风力涡轮机尺寸的变化以及诸如涡流发生器（VG）的流动控制装置的发展有关。在本研究中，对叶片型VG产生的涡流进行了分析。为此，DU 97 W300翼型的空气动力学性能与无VG进行了评估。采用jBAY源项模型对三角形VG进行了模拟，并对全网格计算流体动力学（CFD）模型进行了求解。采用雷诺平均Navier-Stokes方程（RANS）模拟计算了定常状态下涡流发生器的影响，采用分离涡模拟（DES）方法计算了失速状态附近的攻角。所有基于jBAY的数值模拟都是在Re = 2 × 106的雷诺数下进行的，以分析攻角在0 °和20°之间的涡流发生器的影响，并与实验风洞结果进行了验证。结果表明，在翼型上设置VG装置有利于翼型的气动性能，采用jBAY模型进行仿真是准确有效的。
The increased demand for wind power is related to changes in the sizes of wind turbines and the development of flow control devices, such as vortex generators (VGs). In the present study, an analysis of the vortices generated by a vane-type VG is performed. To that end, the aerodynamic performance of a DU97W300 airfoil with and without VG is evaluated. The jBAY source term model was implemented for simulation of a triangular-shaped VG and the resolution of the fully meshed computational fluid dynamics (CFD) model. Reynolds-averaged Navier–Stokes (RANS) based simulations were used to calculate the effect of VGs in steady state, and the detached eddy simulation (DES) method was used for angles of attack (AoAs) around the stall situation. All jBAY based numerical simulations were carried out with a Reynolds number of Re = 2 × 106 to analyze the influence of VGs with AoAs between 0 and 20° and were validated versus experimental wind tunnel results. The results show that setting up a VG device on an airfoil benefits its aerodynamic performance and that the use of the jBAY model for simulation is accurate and efficient.
