Layer formation in horizontally forced stratified turbulence: connecting exact coherent structures to linear instabilities

D Lucas, CP Caulfield, RR Kerswell - Journal of Fluid Mechanics, 2017 - cambridge.org
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 …

Stability of the anabatic Prandtl slope flow in a stably stratified medium

CN **ao, I Senocak - Journal of Fluid Mechanics, 2020 - cambridge.org
In the Prandtl model for anabatic slope flows, a uniform positive buoyancy flux at the surface
drives an upslope flow against a stable background stratification. In the present study, we …
