In particular, in both cases turbulence collapse occurs when \\(Lu_au /u \\lesssim 100\\), suggesting that this is a local process, independent of the details of the outer flow. Analysis of the spectra and energy budgets shows that stable stratification leads to an increase in normalized ...

Energy Balance in Stably-Stratified, Wall-Bounded Turbulence We present DNS of stably-stratified, open-channel flows and capped Ekman layers, where the stable stratification is imposed by ground cooling. These flows have very different outer regions, yet the development of the stratification and t....

Stably stratified turbulence is studied via direct numerical simulations at resolutions up to 1024^3, with the goal of delineating those structures peculiar to stratification, and to examine how such structures influence the decay rate of the turbulence, as well as the transfer of various properties...
We present DNS of stably-stratified, open-channel flows and capped Ekman layers, where the stable stratification is imposed by ground cooling. These flows have very different outer regions, yet the development of the stratification and the flow fields in their buffer regions is very similar. In ...
