Shell Models of Magnetohydrodynamic Turbulence
Franck Plunian, Rodion Stepanov, Peter Frick
Shell models of hydrodynamic turbulence originated in the seventies. Their main aim was to describe the statistics of homogeneous and isotropic turbulence in spectral space, using…
Cascades and dissipation ratio in rotating MHD turbulence at low magnetic Prandtl number
Franck Plunian, Rodion Stepanov
A phenomenology of isotropic magnetohydrodynamic turbulence subject to both rotation and applied magnetic field is presented. It is assumed that the triple correlations decay-time…
Harmonic and subharmonic solutions of the Roberts dynamo problem. Application to the Karlsruhe experiment
F. Plunian, K. -H. Radler
Two different approaches to the Roberts dynamo problem are considered. Firstly, the equations governing the magnetic field are specified to both harmonic and subharmonic solutions…
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…
Impact of impellers on the axisymmetric magnetic mode in the VKS2 dynamo experiment
R. Laguerre, C. Nore, A. Ribeiro +3
In the VKS2 (von Kármán Sodium 2) successful dynamo experiment of September 2006, the magnetic field that was observed showed a strong axisymmetric component, implying that non axi…
