High dimensional tori and chaotic and intermittent transients in magnetohydrodynamic Couette flows
Ferran Garcia, Jude Ogbonna, André Giesecke +1
The magnetised spherical Couette (MSC) problem, a three dimensional magnetohydrodynamic paradigmatic model in geo- and astrophysics, is considered to investigate bifurcations to hi…
Weak branch and multimodal convection in rapidly rotating spheres at low Prandtl number
Ferran Garcia, Frank Stefani, Emmanuel Dormy
The focus of this study is to investigate primary and secondary bifurcations to weakly nonlinear flows (weak branch) in convective rotating spheres in a regime where only strongly…
Modulated rotating waves and triadic resonances in spherical fluid systems: The case of magnetized spherical Couette flow
Ferran Garcia, André Giesecke, Frank Stefani
The existence of triadic resonances in the magnetized spherical Couette system (MSC) is related to the development of modulated rotating waves, which are quasiperiodic flows unders…
Four-frequency solution in a magnetohydrodynamic Couette flow as a consequence of azimuthal symmetry breaking
Ferran Garcia, Martin Seilmayer, André Giesecke +1
The occurrence of magnetohydrodynamic (MHD) quasiperiodic flows with four fundamental frequencies in differentially rotating spherical geometry is understood in terms of a sequence…
Long term time dependent frequency analysis of chaotic waves in the weakly magnetized spherical Couette system
Ferran Garcia, Martin Seilmayer, André Giesecke +1
The long therm behavior of chaotic flows is investigated by means of time dependent frequency analysis. The system under test consists of an electrically conducting fluid, confined…
Chaotic wave dynamics in weakly magnetised spherical Couette flows
Ferran Garcia, Martin Seilmayer, André Giesecke +1
Direct numerical simulations of a liquid metal filling the gap between two concentric spheres are presented. The flow is governed by the interplay between the rotation of the inner…
Continuation and stability of rotating waves in the magnetized spherical Couette system: Secondary transitions and multistability
Ferran Garcia, Frank Stefani
Rotating waves (RW) bifurcating from the axisymmetric basic magnetized spherical Couette (MSC) flow are computed by means of Newton-Krylov continuation techniques for periodic orbi…
