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…
The problem of small and large scale fields in the solar dynamo
A. Brandenburg, N. E. L. Haugen, P. J. Käpylä +1
Three closely related stumbling blocks of solar mean field dynamo theory are discussed: how dominant are the small scale fields, how is the alpha effect quenched, and whether magne…
Local models of stellar convection III: The Strouhal number
P. J. Käpylä, M. J. Korpi, M. Ossendrijver +1
Aims: The Strouhal number (St), which is a nondimensional measure of the correlation time, is determined from numerical models of convection. The Strouhal number arises in the mean…
Local models of stellar convection II: Rotation dependence of the mixing length relations
P. J. Käpylä, M. J. Korpi, M. Stix +1
We study the mixing length concept in comparison to three-dimensional numerical calculations of convection with rotation. In a limited range, the velocity and temperature fluctuati…
