Mean-field dynamos: the old concept and some recent developments
K. -H. Rädler
This article reproduces the Karl Schwarzschild lecture 2013. Some of the basic ideas of electrodynamics and magnetohydrodynamics of mean fields in turbulently moving conducting flu…
Mean-field dynamo action from delayed transport
Matthias Rheinhardt, Ebru Devlen, Karl-Heinz Rädler +1
We analyze the nature of dynamo action that produces horizontally averaged magnetic fields in two particular flows that were studied by Roberts (1972, Phil. Trans. R. Soc. A 271, 4…
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…
Nonlinear magnetic diffusivity and alpha tensors in helical turbulence
A. Brandenburg, K. -H. Rädler, M. Rheinhardt +1
The effect of a dynamo-generated mean magnetic field of Beltrami type on the mean electromotive force is studied. In the absence of the mean magnetic field the turbulence is assume…
Steady dynamos in finite domains: an integral equation approach
Frank Stefani, Gunter Gerbeth, Karl-Heinz Rädler
The paper deals with the integral equation approach to steady kinematic dynamo models in finite domains based on Biot-Savart's law. The role of the electric potential at the bounda…
