Localized layers of turbulence in stratified horizontally sheared Poiseuille flow
Joris Labarbe, Patrice Le Gal, Uwe Harlander +2
This article presents a numerical analysis of the instability developing in horizontally sheared Poiseuille flow, when stratification extends along the vertical direction. Our stud…
Swimming of a ludion in a stratified sea
P. Le Gal, B. Castillo Morales, S. Hernandez Zapata +1
We describe and model experimental results on the dynamics of a "ludion" - a neutrally buoyant body - immersed in a layer of stably stratified salt water. By oscillating a piston i…
The linear instability of the stratified plane Couette flow
Giulio Facchini, Benjamin Favier, Patrice Le Gal +2
We present the stability analysis of a plane Couette flow which is stably stratified in the vertical direction orthogonally to the horizontal shear. Interest in such a flow comes f…
Double-diffusive convection and baroclinic instability in a differentially heated and initially stratified rotating system: the barostrat instability
Miklos Vincze, Ion Borcia, Uwe Harlander +1
A water-filled differentially heated rotating annulus with initially prepared stable vertical salinity profiles is studied in the laboratory. Based on two-dimensional horizontal pa…
The Universal Aspect Ratio of Vortices in Rotating Stratifi?ed Flows: Experiments and Observations
Oriane Aubert, Michael Le Bars, Patrice Le Gal +1
We validate a new law for the aspect ratio of vortices in a rotating, stratified flow, where and are the vertical half-height and horizontal length scale of the vo…
The Universal Aspect Ratio of Vortices in Rotating Stratified Flows: Theory and Simulation
Pedram Hassanzadeh, Philip S. Marcus, Patrice Le Gal
We derive a relationship for the vortex aspect ratio (vertical half-thickness over horizontal length scale) for steady and slowly evolving vortices in rotating stratified fluid…
Magnetic field induced by elliiptical instability in a rotating tidally distorded sphere
P. Le Gal, L. Lacaze, S. Le Dizès
It is usually believed that the geo-dynamo of the Earth or more generally of other planets, is created by the convective fluid motions inside their molten cores. An alternative to…
