Irreversible mixing by unstable periodic orbits in buoyancy dominated stratified turbulence
(Cambridge University PressJournal of Fluid Mechanics, 2017-10-26)We consider turbulence driven by a large-scale horizontal shear in Kolmogorov flow (i.e. with sinusoidal body forcing) and a background linear stable strati cation with buoyancy frequency $N^2_B$ imposed in the third, ...

Layer formation in horizontally forced stratified turbulence: Connecting exact coherent structures to linear instabilities
(Journal of Fluid Mechanics, 2017-12-10)© 2017 Cambridge University Press. We consider turbulence in a stratified 'Kolmogorov' flow, driven by horizontal shear in the form of sinusoidal body forcing in the presence of an imposed background linear stable ...
