摘    要:湍流转捩现象对边界层流动的阻力和热交换特性具有严重影响。准确地预测转捩对工程设计意义重大。近年来发展迅速的转捩模型是一种非常适合工程计算的转捩预报方法。本文将转捩模型分成了4个类型,并对每种转捩模型的发展过程加以阐述。在分析和讨论的基础上,总结了目前转捩模型的发展水平,同时也指出尚存的不足之处,为将来构建新的转捩模型以及相关的转捩研究提供建议。

关 键 词:转捩  转捩模型  工程计算  低雷诺数  间歇因子  层流脉动  不稳定波

Abstract:Laminar-turbulent transition can greatly affect the characteristics of boundary layer flow like skin friction and heat transfer.Predicting transition accurately is of great importance in engineering design.The prediction of transition using transition models which develop quickly during past years is very appropriate in engineering applications.Transition models are divided into four types and each type is reviewed in detail respectively.Conclusions are made based on a-nalysis and discussion about the achievements as well as the drawbacks of transition models now-adays,and some suggestions are proposed for transition research and modeling in the future.
Keywords:laminar-turbulent transition  transition modeling  engineering computation  low Reynolds number  intermittency  laminar fluctuation  instability wave
