Simulations of astrophysical dynamos
Axel Brandenburg
Numerical aspects of dynamos in periodic domains are discussed. Modifications of the solutions by numerically motivated alterations of the equations are being reviewed using the ex…
How can vorticity be produced in irrotationally forced flows?
Fabio Del Sordo, Axel Brandenburg
A spherical hydrodynamical expansion flow can be described as the gradient of a potential. In that case no vorticity should be produced, but several additional mechanisms can drive…
Plasmoid ejections driven by dynamo action underneath a spherical surface
Jörn Warnecke, Axel Brandenburg, Dhrubaditya Mitra
We present a unified three-dimensional model of the convection zone and upper atmosphere of the Sun in spherical geometry. In this model, magnetic fields, generated by a helically…
Dissipation in dynamos at low and high magnetic Prandtl numbers
A. Brandenburg
Using simulations of helically driven turbulence, it is shown that the ratio of kinetic to magnetic energy dissipation scales with the magnetic Prandtl number in power law fashion…
Reynolds stress and heat flux in spherical shell convection
P. J. Käpylä, M. J. Mantere, G. Guerrero +2
(abridged) Context. Turbulent fluxes of angular momentum and heat due to rotationally affected convection play a key role in determining differential rotation of stars. Here we per…
