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…
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…
Turbulent front speed in the Fisher equation: dependence on Damkohler number
A. Brandenburg, N. E. L. Haugen, N. Babkovskaia
Direct numerical simulations and mean-field theory are used to model reactive front propagation in a turbulent medium. In the mean-field approach, memory effects of turbulent diffu…
Vorticity production through rotation, shear and baroclinicity
Fabio Del Sordo, Axel Brandenburg
In the absence of rotation and shear, and under the assumption of constant temperature or specific entropy, purely potential forcing by localized expansion waves is known to produc…
Alleviating alpha quenching by solar wind and meridional flow
Dhrubaditya Mitra, David Moss, Reza Tavakol +1
We study the ability of magnetic helicity expulsion to alleviate catastrophic -quenching in mean field dynamos in two--dimensional spherical wedge domains. Motivated by the phys…
