Acoustic spectra of a gas-filled rotating spheroid
Sylvie Su, David Cébron, Henri-Claude Nataf +4
The acoustic spectrum of a gas-filled resonating cavity can be used to indirectly probe its internal velocity field. This unconventional velocimetry method is particularly interest…
Multiple zonal jets and convective heat transport barriers in a quasi-geostrophic model of planetary cores
Céline Guervilly, Philippe Cardin
We study rapidly-rotating Boussinesq convection driven by internal heating in a full sphere. We use a numerical model based on the quasi-geostrophic approximation for the velocity…
Subcritical convection of liquid metals in a rotating sphere using a quasi-geostrophic model
Celine Guervilly, Philippe Cardin
We study nonlinear convection in a rapidly rotating sphere with internal heating for values of the Prandtl number relevant for liquid metals (). We use a nu…
Experimental evidence of Alfvén wave propagation in a Gallium alloy
Thierry Alboussiere, Philippe Cardin, François Debray +5
Experiments with a liquid metal alloy, galinstan, are reported and show clear evidence of Alfvén wave propagation as well as resonance of Alfvén modes. Galinstan is liquid at room…
Quasi-geostrophic model of the instabilities of the Stewartson layer
Nathanael Schaeffer, Philippe Cardin
We study the destabilization of a shear layer, produced by differential rotation of a rotating axisymmetric container. For small forcing, this produces a shear layer, which has bee…
