Inertial wave super-attractor in a truncated elliptical cone
Benjamin Favier, Stéphane Le Dizès
We consider inertial waves propagating in a fluid contained in a non-axisymmetric three-dimensional rotating cavity. We focus on the particular case of a fluid enclosed inside a tr…
Internal shear layers in librating spherical shells: the case of attractors
Jiyang He, Benjamin Favier, Michel Rieutord +1
Following our previous work on periodic ray paths (He et al, 2022), we study asymptotically and numerically the structure of internal shear layers for very small Ekman numbers in a…
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…
Closely spaced co-rotating helical vortices: Long-wave instability
Andrés Castillo-Castellanos, Stéphane Le Dizès
We consider as base flow the stationary vortex filament solution obtained by Castillo- Castellanos et al. (2021) in the far-wake of a rotor with tip-splitting blades. The cases of…
Zonal flow in a resonant precessing cylinder
Donglai Gao, Patrice Meunier, Stéphane Le Dizès +1
A cylinder undergoes precession when it rotates around its axis and this axis itself rotates around another direction. In a precessing cylinder full of fluid, a steady and axisymme…
Closely spaced co-rotating helical vortices: General solutions
Andrés Castillo-Castellanos, Eduardo Durán Venegas, Stéphane Le Dizès
In this work, we present general solutions for closely spaced co-rotating helical vortices using a filament approach. For these vortex structures, helical symmetry is broken, but s…
Vortices in stratified protoplanetary disks : From baroclinic instability to vortex layers
P. Barge, S. Richard, S. Le Dizes
Large scale vortices could play a key role in the evolution of protoplanetary disks, particularly in the dead-zone where no turbulence associated with magnetic field is expected. T…
Structure, stability and evolution of 3D Rossby vortices in protoplanetary disks
Samuel Richard, Pierre Barge, Stephane Le Dizes
Large-scale persistent vortices are known to form easily in 2D disks via the Rossby wave or the baroclinic instability. In 3D, however, their formation and stability is a complex i…
Libration-induced mean flow in a spherical shell
Alban Sauret, Stéphane Le Dizès
We investigate the flow in a spherical shell subject to a time harmonic oscillation of its rotation rate, also called longitudinal libration, when the oscillation frequency is larg…
Fluid flows in a librating cylinder
Alban Sauret, David Cébron, Michael Le Bars +1
The flow in a cylinder driven by time harmonic oscillations of the rotation rate, called longitudinal librations, is investigated. Using a theoretical approach and axisymmetric num…
Elliptical instability of a flow in a rotating shell
L. Lacaze, P. Le Gal, S. Le Dizès
A theoretical and experimental study of the spin-over mode induced by the elliptical instability of a flow contained in a slightly deformed rotating spherical shell is presented. T…
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…
On the three-dimensional temporal spectrum of stretched vortices
M. Rossi, S. Le Dizes
The three-dimensional stability problem of a stretched stationary vortex is addressed in this letter. More specifically, we prove that the discrete part of the temporal spectrum is…
