Sheared helical turbulence and the helicity constraint in large-scale dynamos
A. Bigazzi, A. Brandenburg, K. Subramanian
The effect of shear on the growth of large scale magnetic fields in helical turbulence is investigated. The resulting large-scale magnetic field is also helical and continues to ev…
The inverse cascade in turbulent dynamos
Axel Brandenburg
The emergence of a large scale magnetic field from randomly forced isotropic strongly helical flows is discussed in terms of the inverse cascade of magnetic helicity and the alpha-…
Two-dimensional disk dynamos with vertical outflows into a halo
B. von Rekowski, W. Dobler, A. Shukurov +1
We study the effects of vertical outflows on mean-field dynamos in disks. These outflows could be due to thermal winds or magnetic buoyancy. We analyse numerical solutions of the n…
The solar dynamo: old, recent, and new problems
Axel Brandenburg
A number of problems of solar and stellar dynamo theory are briefly reviewed and the current status of possible solutions is discussed. Results of direct numerical simulations are…
Inverse cascade in decaying 3D magnetohydrodynamic turbulence
Mattias Christensson, Mark Hindmarsh, Axel Brandenburg
We perform direct numerical simulations of three-dimensional freely decaying magnetohydrodynamic (MHD) turbulence. For helical magnetic fields an inverse cascade effect is observed…
The helicity constraint in turbulent dynamos with shear
Axel Brandenburg, Alberto Bigazzi, Kandaswamy Subramanian
The evolution of magnetic fields is studied using simulations of forced helical turbulence with strong imposed shear. After some initial exponential growth, the magnetic field deve…
