TLDR
In this article, the authors investigated the effect of small and large-scale motions on the counter-gradient heat transfer in unsheared water flows downstream of turbulence-generation grids, and the results showed that the difference of turbulent diffusion between heat (active scalar) and mass (passive scalar), with different molecular diffusivities in thermally stratified water flows appears in the highfrequency region, and it results in a slightly larger turbulent mass flux than heat flux in strong stratification.About:

Statistically stationary differential diffusion in a large-scale internal waves vortical modes environment
TL;DR: In this paper, a theory for differential diffusion of heat and salt in a statistically stationary large-scale internal wave environment has been developed, which complements recent laboratory and numerical studies where turbulence is generated impulsively.

A numerical study of the evolution and structure of homogeneous stably stratified sheared turbulence
TL;DR: In this paper, the structure and evolution of homogeneous stably stratified sheared turbulence have been investigated through direct numerical simulation, where the primary dimensionless parameter is the Richardson number which measures the relative importance of stratification and mean shear.

Turbulence structure in stably stratified open-channel flow
TL;DR: In this article, the effects of stable stratification on turbulence structure have been experimentally investigated in stratified open-channel flow and a theoretical spectral-equation model has been applied to the stably stratified flow.
