Yoshizawa's cross-helicity effect and its quenching
A. Brandenburg, K. -H. Rädler
A central quantity in mean-field magnetohydrodynamics is the mean electromotive force EMF, which in general depends on the mean magnetic field. It may however have a part independe…
Mean-field diffusivities in passive scalar and magnetic transport in irrotational flows
Karl-Heinz Rädler, Axel Brandenburg, Fabio Del Sordo +1
Certain aspects of the mean-field theory of turbulent passive scalar transport and of mean-field electrodynamics are considered with particular emphasis on aspects of compressible…
Mean electromotive force proportional to mean flow in mhd turbulence
K. -H. Rädler, A. Brandenburg
In mean-field magnetohydrodynamics the mean electromotive force due to velocity and magnetic field fluctuations plays a crucial role. In general it consists of two parts, one indep…
Mean-field effects in the Galloway-Proctor flow
Karl-Heinz Rädler, Axel Brandenburg
The coefficients defining the mean electromotive force in a Galloway-Proctor flow are determined. This flow shows a two-dimensional pattern and is helical. The pattern wobbles in i…
Magnetic diffusivity tensor and dynamo effects in rotating and shearing turbulence
A. Brandenburg, K. -H. Rädler, M. Rheinhardt +1
The turbulent magnetic diffusivity tensor is determined in the presence of rotation or shear. The question is addressed whether dynamo action from the shear-current effect can expl…
Mean--field electrodynamics: Critical analysis of various analytical approaches to the mean electromotive force
Karl-Heinz Raedler, Matthias Rheinhardt
There are various analytical approaches to the mean electromotive force crucial in mean--field electrodynamics, with and bein…
The mean electromotive force due to turbulence of a conducting fluid in the presence of mean flow
Karl-Heinz Readler, Rodion Stepanov
The mean electromotive force caused by turbulence of an electrically conducting fluid, which plays a central part in mean--field electrodynamics, is calculated for a rotating fluid…
The Mean Electromotive Force for MHD Turbulence: the Case of a Weak Mean Magnetic Field and Slow Rotation
K-H. Raedler, N. Kleeorin, I. Rogachevskii
The mean electromotive force in the framework of mean--field magnetohydrodynamics is found with a particular attention to the effect of a mean rotation of the fluid on the mean ele…
Contributions to the theory of a two-scale homogeneous dynamo experiment
Karl-Heinz Raedler, Axel Brandenburg
The principle of the Karlsruhe dynamo experiment is closely related to that of the Roberts dynamo working with a simple fluid flow which is, with respect to proper Cartesian co-ord…
