Lambda-effect from forced turbulence simulations
P. J. Käpylä, A. Brandenburg
Aims: We determine the components of the -effect tensor that quantifies the contributions to the turbulent momentum transport even for uniform rotation. Methods: Three-dimension…
Large-scale dynamos in turbulent convection with shear
P. J. Käpylä, M. J. Korpi, A. Brandenburg
(abridged) Aims: Three-dimensional numerical simulations of penetrative compressible convection with uniform horizontal shear are used to study dynamo action and the generation of…
Minimal tau approximation and simulations of the alpha effect
A. Brandenburg, K. Subramanian
The validity of a closure called the minimal tau approximation (MTA), is tested in the context of dynamo theory, wherein triple correlations are assumed to provide relaxation of th…
Hydrodynamic and hydromagnetic energy spectra from large eddy simulations
N. E. L. Haugen, A. Brandenburg
Direct and large eddy simulations of hydrodynamic and hydromagnetic turbulence have been performed in an attempt to isolate artifacts from real and possibly asymptotic features in…
MHD simulations of small and large scale dynamos
A. Brandenburg, N. E. L. Haugen, W. Dobler
Isotropic homogeneous hydromagnetic turbulence is studied using numerical simulations at resolutions of up to 1024^3 meshpoints. It is argued that, in contrast to the kinematic reg…
Turbulent magnetic Prandtl number and magnetic diffusivity quenching from simulations
T. A. Yousef, A. Brandenburg, G. Rüdiger
Forced turbulence simulations are used to determine the turbulent kinematic viscosity, nu_t, from the decay rate of a large scale velocity field. Likewise, the turbulent magnetic d…
