Large-scale dynamos in rigidly rotating turbulent convection
P. J. Käpylä, M. J. Korpi, A. Brandenburg
The existence of large-scale dynamos in rigidly rotating turbulent convection without shear is studied using three-dimensional numerical simulations of penetrative rotating compres…
Turbulent dynamos with shear and fractional helicity
P. J. Käpylä, A. Brandenburg
Dynamo action owing to helically forced turbulence and large-scale shear is studied using direct numerical simulations. The resulting magnetic field displays propagating wave-like…
The helicity constraint in spherical shell dynamos
A. Brandenburg, P. J. Käpylä, D. Mitra +2
The motivation for considering distributed large scale dynamos in the solar context is reviewed in connection with the magnetic helicity constraint. Preliminary accounts of 3-dimen…
Turbulent viscosity and Lambda-effect from numerical turbulence models
P. J. Käpylä, A. Brandenburg
Homogeneous anisotropic turbulence simulations are used to determine off-diagonal components of the Reynolds stress tensor and its parameterization in terms of turbulent viscosity…
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…
Effects of Rotation and Input Energy Flux on Convective Overshooting
P. J. Käpylä, M. J. Korpi, M. Stix +1
We study convective overshooting by means of local 3D convection calculations. Using a mixing length model of the solar convection zone (CZ) as a guide, we determine the Coriolis n…
