Cylindrical anisotropic dynamos
R. Avalos-Zuñiga, M. Xu, F. Stefani +2
We explore the influence of geometry variations on the structure and the time-dependence of the magnetic field that is induced by kinematic dynamos in a finite cylinder. Th…
Influence of electromagnetic boundary conditions onto the onset of dynamo action in laboratory experiments
R. Avalos-Zuniga, F. Plunian
We study the onset of dynamo action of the Riga and Karlsruhe experiments with the addition of an external wall, the electro-magnetic properties of which being different from those…
An optimal scale separation for a dynamo experiment
Franck Plunian
Scale separation between the flow and the magnetic field is a common feature of natural dynamos. It has also been used in the Karlsruhe sodium experiment in which the scale of the…
Oscillating Ponomarenko dynamo in the highly conducting limit
Marine Peyrot, Andrew Gilbert, Franck Plunian
This paper considers dynamo action in smooth helical flows in cylindrical geometry, otherwise known as Ponomarenko dynamos, with periodic time dependence. An asymptotic framework i…
