涡流发生器（Vortex Generator，VG）通常放置在风力涡轮机叶片上以延迟边界层中的流动分离。在计算流体动力学中，可以对VG进行参数化建模，以有效地和高效地模拟风力叶片流场。许多研究者对涡流发生器产生的涡环进行了研究，建立了各种基于Navier-Stokes方程的参数化模型，但大多数模型都是基于单个涡流发生器的小翼，没有考虑小翼之间的相互影响。本文提出了一种基于反向旋转矢量发生器的矢量发生器阵列参数化模型，该模型适当地考虑了翼梢小翼之间的相互影响。两种情况，即，一个带有一对涡流发生器的平板和一个带有五对涡流发生器的DU-W2-250叶片段，对该模型进行了验证，与传统模型相比，阵列式参数模型更接近实验数据。与固体VG模型相比，阵列型模型具有相似的流线和表面压力系数。
Vortex generators (VGs) are commonly placed on wind turbine blades to delay flow separation in the boundary layer. VGs can be parametrically modeled in computational fluid dynamics for effective and efficient simulations of wind blade flow fields. Many researchers have studied the vortex circulation created by VGs and created various parametric models used with the Navier-Stokes equations, but most of them are based on a single winglet of VGs and do not include the inter-effects between the winglets. This paper proposes a parameterized VG array model based on counter-rotating VGs, which properly takes into account the inter-effects between winglets. Two cases, i.e., a plate with a pair of VGs and a DU-W2–250 blade segment with five pairs of VGs, are investigated to validate this model; the array type parametric model is in closer agreement with experimental data than traditional models. Compared to the solid VG model, the array type model has similar streamlines and surface pressure coefficients on the su...
