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
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.关键词
