Magneto--Coriolis waves in a spherical Couette flow experiment
Denys Schmitt, Philippe Cardin, Patrick La Rizza +1
The dynamics of fluctuations in a fast rotating spherical Couette flow experiment in the presence of a strong dipolar magnetic field is investigated in detail, through a thorough a…
Modes and instabilities in magnetized spherical Couette flow
Aldo Figueroa, Nathanaël Schaeffer, Henri-Claude Nataf +1
Several teams have reported peculiar frequency spectra for flows in a spherical shell. To address their origin, we perform numerical simulations of the spherical Couette flow in a…
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…
Zonal shear and super-rotation in a magnetized spherical Couette flow experiment
Daniel Brito, Thierry Alboussière, Philippe Cardin +6
We present measurements performed in a spherical shell filled with liquid sodium, where a 74 mm-radius inner sphere is rotated while a 210 mm-radius outer sphere is at rest. The in…
Rapidly rotating spherical Couette flow in a dipolar magnetic field: an experimental study of the mean axisymmetric flow
Henri-Claude Nataf, Thierry Alboussiere, Daniel Brito +4
In order to explore the magnetostrophic regime expected for planetary cores, experiments have been conducted in a rotating sphere filled with liquid sodium, with an imposed dipolar…
Experimental study of super-rotation in a magnetostrophic spherical Couette flow
Henri-Claude Nataf, Thierry Alboussière, Daniel Brito +5
We report measurements of electric potentials at the surface of a spherical container of liquid sodium in which a magnetized inner core is differentially rotating. The azimuthal an…
