Mean Field Electrodynamics: Triumphs and Tribulations
David W. Hughes
The theory of mean field electrodynamics, now celebrating its fiftieth birthday, has had a profound influence on our modelling of cosmical dynamos, greatly enhancing our understand…
Scale Selection in the Stratified Convection of the Solar Photosphere
M. Kessar, D. W. Hughes, E. Kersale +2
We examine the role of stratification in determining the scale for turbulent anelastic convection. Motivated by the range of scales observed in convection at the solar photosphere,…
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…
Large-scale-vortex dynamos in planar rotating convection
Céline Guervilly, David W. Hughes, Chris A. Jones
Several recent studies have demonstrated how large-scale vortices may arise spontaneously in rotating planar convection. Here we examine the dynamo properties of such flows in rota…
Strong field dynamo action in rapidly rotating convection with no inertia
David W. Hughes, Fausto Cattaneo
The Earth's magnetic field is generated by dynamo action driven by convection in the outer core. For numerical reasons, inertial and viscous forces play an important role in geodyn…
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…
