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…
Diffusionless hydromagnetic modes in rotating ellipsoids: a road to weakly nonlinear models?
Jérémie Vidal, David Cébron, Nathanaël Schaeffer
We investigate free hydromagnetic eigenmodes of an incompressible, inviscid and ideal electrically conducting fluid in rotating triaxial ellipsoids. The container rotates with an a…
Bistable flows in precessing spheroids
D Cébron
Precession driven flows are found in any rotating container filled with liquid, when the rotation axis itself rotates about a secondary axis that is fixed in an inertial frame of r…
Magnetic induction and diffusion mechanisms in a liquid sodium spherical Couette experiment
Simon Cabanes, Nathanaël Schaeffer, Henri-Claude Nataf
We present a reconstruction of the mean axisymmetric azimuthal and meridional flows in the DTS liquid sodium experiment. The experimental device sets a spherical Couette flow enclo…
Shell Models of Magnetohydrodynamic Turbulence
Franck Plunian, Rodion Stepanov, Peter Frick
Shell models of hydrodynamic turbulence originated in the seventies. Their main aim was to describe the statistics of homogeneous and isotropic turbulence in spectral space, using…
