The spectrum of the Poincar{é} operator in an ellipsoid
Yves Colin de Verdière, Jérémie Vidal
We study the spectrum of the Poincaré operator in triaxial ellipsoids subject to a constant rotation. As explained in the paper, this mathematical problem is interesting for many p…
Precession-driven flows in stress-free ellipsoids
J. Vidal, D. Cébron
Motivated by modelling rotating turbulence in planetary fluid layers, we investigate precession-driven flows in ellipsoids subject to stress-free boundary conditions (SF-BC). The S…
Kinematic dynamos in triaxial ellipsoids
Jérémie Vidal, David Cébron
Planetary magnetic fields are generated by motions of electrically conducting fluids in their interiors. The dynamo problem has thus received much attention in spherical geometries…
Acoustic and inertial modes in planetary-like rotating ellipsoids
Jérémie Vidal, David Cébron
The bounded oscillations of rotating fluid-filled ellipsoids can provide physical insight into the flow dynamics of deformed planetary interiors. The inertial modes, sustained by t…
Acoustic modes of rapidly rotating ellipsoids subject to centrifugal gravity
Jérémie Vidal, David Cébron
The acoustic modes of a rotating fluid-filled cavity can be used to determine the effective rotation rate of a fluid (since the resonant frequencies are modified by the flows). To…
Mean zonal flows induced by weak mechanical forcings in rotating spheroids
David Cébron, Jérémie Vidal, Nathanaël Schaeffer +2
The generation of mean flows is a long-standing issue in rotating fluids. Motivated by planetary objects, we consider here a rapidly rotating fluid-filled spheroid, which is subjec…
