高超声速三维边界层转捩数值研究进展及预测软件

Numerical research progress and prediction software of transition in hypersonic three-dimensional boundary layer

  • 摘要: 高超声速边界层转捩问题已经成为飞行器设计需要考虑的一个关键因素,也是高超声速流动研究的热点和难点。三维边界层中存在横流、流向涡、接触线三种典型的流动结构和失稳特征,他们诱导转捩的机理不同。本文总结了低雷诺数湍流、γ-Reθtk-ω-γ、层流动能4种常用转捩模型的构造、适用性及应用情况,介绍了适用于三维边界层的BiGlobal、PSE3D、TriGlobal三种全局稳定性分析方法,分析了基于转捩预测eN方法的eMalik、LASTRAC、LILO、HyTEN等转捩软件的优缺点,展望了高超声速三维边界层转捩研究及软件开发的未来。

     

    Abstract: Hypersonic boundary layer transition has become a key factor to be considered in aircraft design, and is also a hot and difficult point in hypersonic flow research. There are three typical flow structures and instability characteristics in hypersonic three-dimensional boundary layer, namely cross flow, flow direction vortex and contact line, which have different mechanisms to induce transition. Three global stability analysis methods (BiGlobal, PSE3D and TriGlobal) suitable for three-dimensional boundary layer are introduced. The structure, applicability and application of four commonly used transition models, such as the Low-Reynolds-Number turbulence model, γ-Reθt , k-ω-γ , laminar-kinetic energy transition model, are summarized. The advantages and disadvantages of eMalik, LASTRAC, LILO, HyTEN and other transition softwares based on eN method are analyzed. The future of transition research and software development in hypersonic three-dimensional boundary layer is prospected.
