Growth rate of small-scale dynamo at low magnetic Prandtl numbers
N. Kleeorin, I. Rogachevskii
In this study we discuss two key issues related to a small-scale dynamo instability at low magnetic Prandtl numbers and large magnetic Reynolds numbers, namely: (i) the scaling for…
Detection of negative effective magnetic pressure instability in turbulence simulations
Axel Brandenburg, Koen Kemel, Nathan Kleeorin +2
We present the first demonstration of the negative effective magnetic pressure instability in direct numerical simulations of stably stratified, externally forced, isothermal hydro…
A hierarchy of energy- and flux-budget (EFB) turbulence closure models for stably stratified geophysical flows
S. S. Zilitinkevich, T. Elperin, N. Kleeorin +2
In this paper we advance physical background of the energy- and flux-budget turbulence closure based on the budget equations for the turbulent kinetic and potential energies and tu…
Current helicity of active regions as a tracer of large-scale solar magnetic helicity
H. Zhang, D. Moss, N. Kleeorin +5
We demonstrate that the current helicity observed in solar active regions traces the magnetic helicity of the large-scale dynamo generated field. We use an advanced 2D mean-field d…
Properties of the negative effective magnetic pressure instability
K. Kemel, A. Brandenburg, N. Kleeorin +1
As was demonstrated in earlier studies, turbulence can result in a negative contribution to the effective mean magnetic pressure, which, in turn, can cause a large-scale instabilit…
Pumping velocity in homogeneous helical turbulence with shear
I. Rogachevskii, N. Kleeorin, P. Käpylä +1
Using different analytical methods (the quasi-linear approach, the path-integral technique and tau-relaxation approximation) we develop a comprehensive mean-field theory for a pump…
