Scale dependence of alpha effect and turbulent diffusivity
A. Brandenburg, K. -H. Rädler, M. Schrinner
Aims: To determine alpha effect and turbulent magnetic diffusivity for mean magnetic fields with profiles of different length scale from simulations of isotropic turbulence, and to…
Alpha-effect dynamos with zero kinetic helicity
Karl-Heinz Rädler, Axel Brandenburg
A simple explicit example of a Roberts-type dynamo is given in which the alpha-effect of mean-field electrodynamics exists in spite of point-wise vanishing kinetic helicity of the…
Mean-field concept and direct numerical simulations of rotating magnetoconvection and the geodynamo
M. Schrinner, K. -H. Raedler, D. Schmitt +2
A comparison is made between mean-field models and direct numerical simulations of rotating magnetoconvection and the geodynamo. The mean-field coefficients are calculated with the…
On the effects of turbulence on a screw dynamo
K. -H. Raedler, R. Stepanov
In an experiment in the Institute of Continuous Media Mechanics in Perm (Russia) an non--stationary screw dynamo is intended to be realized with a helical flow of liquid sodium in…
