Subcritical dynamos in rapidly-rotating planar convection
Robert G. Cooper, Paul J. Bushby, Celine Guervilly
We study dynamo action using numerical simulations of planar Boussinesq convection at rapid rotation (low Ekman numbers, Ek), focusing on subcritical dynamo action in which the dyn…
Subcritical turbulent condensate in rapidly rotating Rayleigh-Bénard convection
Benjamin Favier, Céline Guervilly, Edgar Knobloch
The possibility of subcritical behaviour in the geostrophic turbulence regime of rapidly rotating thermally driven convection is explored. In this regime a non-local inverse energy…
Jets and large-scale vortices in rotating Rayleigh-Bénard convection
Céline Guervilly, David W. Hughes
One of the most prominent dynamical features of turbulent, rapidly-rotating convection is the formation of large-scale coherent structures, driven by Reynolds stresses resulting fr…
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…
Generation of magnetic fields by large-scale vortices in rotating convection
Celine Guervilly, David W. Hughes, Chris A. Jones
We propose a new self-consistent dynamo mechanism for the generation of large-scale magnetic fields in natural objects. Recent computational studies have described the formation of…
Self-consistent simulations of a von Kármán type dynamo in a spherical domain with metallic walls
Céline Guervilly, Nicholas H. Brummell
We have performed numerical simulations of boundary-driven dynamos using a three-dimensional non-linear magnetohydrodynamical model in a spherical shell geometry. A conducting flui…
