摘要:

本文总结了近60 年来分层流动中湍流特性研究的成果. 主要从两个方面进行了综述:(1) 分层流动中湍流场的演变和混合. 在这方面主要分析稳定分层对湍流混合和湍流结构的影响, 以及混合层内湍流结构的特性和混合层的演化规律. (2) 分层流动中湍流的扩散和输运. 动量和标量的逆梯度输运特性是分层湍流研究的一个重要方向;分析分层对湍流扩散的影响. 并指出了一些值得今后进一步研究的方向.

Abstract:

Advances in the past 60 years in the research of the characteristics in turbulent stratification is summarized in this presentation. The paper is mainly described into two parts: (1) Turbulence evolution and mixing in stratified fiuid. The effects of stable stratification on turbulent mixing and structure are mainly analyzed; The evolution of the mixing layer and the turbulent structures in the mixing layer are taken account; (2) Turbulence diffusion and transfer in stratified. Counter gradient transport phenomena for momentum and scalar in stably stratified flows are an important subject in the research of stratified turbulence; Effect of stable stratification on turbulence diffusion is studied. Finally some subjects for further studies are suggested.

Key words:

stratified turbulence|mixing layer|anisotropy|turbulent mixing|scalar transport|counter gradient transport
