Stratified turbulence
  KTH/Nordita/SU seminar in Theoretical Physics [before December 2013]

Wednesday 29 November 2006
from 11:00 to 12:00
at AlbaNova ( FB41 )
Speaker : Geert Brethouwer (Dept. of Mechanics, KTH)
Abstract : Stable and strong stratification is a common phenomenon in the atmosphere, oceans and lakes. Owing to their importance for the understanding of geophysical flows, stratified flows have been investigated in many theoretical, experimental and numerical studies. We have carried out direct numerical simulations of stably and strongly stratified turbulent flows and interpreted the results on basis of a scaling analysis of the governing equations. The analysis suggests that there are two different strongly stratified regimes and this is confirmed by the numerical simulations.
