Can the dynamo of spiral-arm galaxies be explained by anisotropic conductivity ?
Paul Gomez, Franck Plunian, Thierry Alboussière
The possibility of generating a magnetic field by dynamo effect with anisotropic electrical conductivity rather than turbulent flow has been demonstrated theoretically (Plunian & A…
Fast and Furious dynamo action in the anisotropic dynamo
Franck Plunian, Thierry Alboussière
In the limit of large magnetic Reynolds numbers, it is shown that a smooth differential rotation can lead to fast dynamo action, provided that the electrical conductivity or magnet…
Fury: an experimental dynamo with anisotropic electrical conductivity
Thierry Alboussière, Franck Plunian, Marc Moulin
We report measurements of dynamo action in a new experimental setup, named Fury, based on the use of an anisotropic electrical conductivity. It consists in a copper rotor rotating…
Axisymmetric dynamo action produced by differential rotation, with anisotropic electrical conductivity and anisotropic magnetic permeability
Franck Plunian, Thierry Alboussière
The effect on dynamo action of an anisotropic electrical conductivity conjugated to an anisotropic magnetic permeability is considered. Not only is the dynamo fully axisymmetric, b…
Inverse cascade of energy in helical turbulence
Franck Plunian, Andrei Teimurazov, Rodion Stepanov +1
Using direct numerical simulation of hydrodynamic turbulence with helicity forcing applied at all scales, a near-maximum helical turbulent state is obtained, with an inverse energy…
Dynamo action in sliding plates of anisotropic electrical conductivity
Thierry Alboussiere, Kamel Drif, Franck Plunian
With materials of anisotropic electrical conductivity, it is possible to generate a dynamo with a simple velocity field, of the type precluded by Cowling's theorems with isotropic…
