为提高涡流发生器（VG）参数化模型计算精度,对参数化模型的应用方法进行研究。首先提出参数化模型在计算域作为源项而添加的位置和涡核半径取值方法。然后,采用考虑VG叶片间影响的最大涡环量算法,基于DU91-W2-250叶段,从不同VG间距、VG入流角、翼型攻角来比对参数化模型和实体模型的计算结果,来验证应用上述方法的可行性。结果表明：参数化模型、实体模型与试验数据吻合良好,证明了两种模拟方法精度较高;此外,在不同工况下,两种模型得到的速度矢量和边界层速度型都具有较高的一致性,证明参数化模拟方法有效,且在风力机叶片上具有普适性。
Abstract
In order to improve the calculation accuracy of the vortex generator（VG）parametric model, the parametric model application method was studied. Firstly, the method for the adding position of source term in the calculation domain and value of vortex core radius were proposed. Then, based on DU91-W2-250 blade segment, the maximum vorticity circulation algorithm considering the interaction of VG blades was used to compare the calculation results of the parametric model and the entity model under different VG spacings, VG inflow angles and airfoil angles of attack to verify the application feasibility of the above method. The results show that the parametric model and entity model are in good agreement with the experimental data, which proves that the high accuracy of the two simulation methods. In addition, under different working conditions, the velocity vectors and boundary layer velocity profiles obtained by the two models have high consistency, which proves that the parametric simulation method is effective and universal for wind turbine blades.
