Turbulent magnetic Prandtl numbers obtained with MHD Taylor-Couette flow experiments
M. Gellert, G. Ruediger
The stability problem of MHD Taylor-Couette flows with toroidal magnetic fields is considered in dependence on the magnetic Prandtl number. Only the most uniform (but not current-f…
Toroidal field instability and eddy viscosity in Taylor-Couette flows
M. Gellert, G. Rüdiger
Toroidal magnetic fields subject to the Tayler instability can transport angular momentum. We show that the Maxwell and Reynolds stress of the nonaxisymmetric field pattern depend…
Stratorotational instability in Taylor-Couette flow heated from above
M. Gellert, G. Rüdiger
We investigate the instability and nonlinear saturation of temperature-stratified Taylor-Couette flows in a finite height cylindrical gap and calculate angular-momentum transport i…
Energy distribution in nonaxisymmetric magnetic Taylor-Couette flow
M. Gellert, G. Ruediger, A. Fournier
Azimuthal magnetorotational instability is a mechanism that generates nonaxisymmetric field pattern. Nonlinear simulations in an infinite Taylor-Couette system with current-free ex…
Helicity generation and alpha-effect by Vandakurov-Tayler instability with z-dependent differential rotation
M. Gellert, G. Rüdiger, D. Elstner
We investigate in isothermal MHD simulations the instability of toroidal magnetic fields resulting by the action of z-dependent differential rotation on a given axial field B^0 in…
