摘要: 涡流发生器(Vortex generators,VGs)参数化模型可以有效提高加VGs风力机叶片的数值模拟效率。目前VGs参数化模型存在精度低,适用性差等问题。为了提高VGs参数化模型在叶段上的应用精度,提出了VGs参数化模型的应用方法,如源项添加方法、位置及源项区域网格。基于阵列式VGs参数化模型、Lamb-Oseen涡模型和上述应用方法,以加VGs的DU91-W2-250叶段为研究对象,进行模拟研究。参数化模拟数据与VGs实体模型、文献试验结果进行了对比验证,结果显示三者吻合良好,证明了模拟方法有效性和数据可信性。在不同来流风速和来流攻角下,对用参数化建模和实体建模的数值结果进行对比分析,来验证模拟方法对运行工况的普适性。研究结果表明:两种模型计算得到的涡结构和压力系数分布,在整体上都具有较高的一致性,且受来流功角和来流风速影响较小,证明参数化模型有较高的精度和普适性,可以代替实体模型在风力机叶段上应用。

Abstract: The VGs(Vortex generators) parametric model of can effectively improve the numerical simulation efficiency of wind turbine blades with VGs. At present, the VGs parametric model has some problems such as low accuracy and poor applicability. In order to improve the application accuracy of VGs parametric model on blade segment, the application methods of VGs parametric model are proposed, such as source term adding method, location and the grid of source term region. Based on the array VGs parametric model, Lamb-Oseen vortex model and the above application methods, the DU91-w2-250 blade with VGS is taken as the research object. The parametric simulation data are compared with the VGs solid model and the literature test results, and the results show that the three are in good agreement, which proves the effectiveness of the simulation method and the credibility of the data. The numerical results of parametric modeling and solid modeling are compared and analyzed at different incoming wind velocities and angle of attack to verify the universality of the simulation method under operating conditions. The research results show that:the vortex structure and pressure coefficient distribution calculated by the two models have high consistency on the whole, and are less affected by the incoming flow power angle and the incoming wind velocities, which proves that the parametric model has high accuracy and universality, and can be applied to wind turbine blade instead of solid model.

Key words: vortex generator, parametric modeling method, numerical simulation, wind turbine, DU91-W2-250
