Magnetic Dynamo Driven by Inertial Waves
A. Mishra, G. Mamatsashvili, M. Le Bars +2
We demonstrate, by studying precession-driven flows, that inertial wave hydrodynamic turbulence can drive a robust magnetic dynamo action. Motivated by the stronger damping of larg…
Relative dispersion and eddy diffusivity in laboratory experiments of -plane turbulence
Daphné Lemasquerier, Matthew Burke, Benjamin Favier +2
We present the first experimental measures of relative dispersion and turbulent diffusion in rapidly-rotating turbulence in the zonostrophic regime, i.e., in the presence of instan…
Interaction between forced and natural convection in a thin cylindrical fluid layer at low Prandtl number
Florian Rein, Laure Carénini, Florian Fichot +2
Motivated by nuclear safety issues, we study the heat transfers in a thin cylindrical fluid layer with imposed fluxes at the bottom and top surfaces (not necessarily equal) and a f…
Effects of particle size and background rotation on the settling of particle clouds
Quentin Kriaa, Eliot Subra, Benjamin Favier +1
We experimentally investigate the behaviour of instantaneous localised releases of heavy particles falling as turbulent clouds in quiescent water, both with and without background…
Zonal jets experiments in the gas giants' zonostrophic regime
Daphné Lemasquerier, Benjamin Favier, Michael Le Bars
Intense east-west winds called zonal jets are observed in the atmospheres of Jupiter and Saturn and extend in their deep interior. We present experimental results from a fully thre…
Parametric instability and wave turbulence driven by tidal excitation of internal waves
Thomas Le Reun, Benjamin Favier, Michael Le Bars
We investigate the stability of stratified fluid layers undergoing homogeneous and periodic tidal deformation. We first introduce a local model which allows to study velocity and b…
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…
Numerical Simulations of Internal Wave Generation by Convection in Water
Daniel Lecoanet, Michael Le Bars, Keaton J. Burns +4
Water's density maximum at 4C makes it well suited to study internal gravity wave excitation by convection: an increasing temperature profile is unstable to convection below 4C, bu…
Finite-size effects in parametric subharmonic instability
Baptiste Bourget, Hélène Scolan, Thierry Dauxois +3
The parametric subharmonic instability in stratified fluids depends on the frequency and the amplitude of the primary plane wave. In this paper, we present experimental and numeric…
Spontaneous generation of inertial waves from boundary turbulence in a librating sphere
Alban Sauret, David Cébron, Michael Le Bars
In this work, we report the excitation of inertial waves in a librating sphere even for libration frequencies where these waves are not directly forced. This spontaneous generation…
Magnetohydrodynamic simulations of the elliptical instability in triaxial ellipsoids
David Cébron, Michael Le Bars, Pierre Maubert +1
The elliptical instability can take place in planetary cores and stars elliptically deformed by gravitational effects, where it generates large-scale three-dimensional flows assume…
Elliptical instability in hot Jupiter systems
David Cébron, Michael Le Bars, Patrice Le Gal +3
Several studies have already considered the influence of tides on the evolution of systems composed of a star and a close-in companion to tentatively explain different observations…
Libration driven elliptical instability
David Cébron, Michael Le Bars, J. Noir +1
The elliptical instability is a generic instability which takes place in any rotating flow whose streamlines are elliptically deformed. Up to now, it has been widely studied in the…
Elliptical instability in terrestrial planets and moons
David Cébron, Michael Le Bars, Claire Moutou +1
The presence of celestial companions means that any planet may be subject to three kinds of harmonic mechanical forcing: tides, precession/nutation, and libration. These forcings c…
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…
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…
