REVIEW ON STUDY OF TURBULENT CHARACTERISTICS IN STRATIFIED FLOW

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.
