Cross-helicity effect on -type dynamo in non-equilibrium turbulence
Krzysztof A. Mizerski, Nobumitsu Yokoi, Axel Brandenburg
Turbulence is typically not in equilibrium, i.e. mean quantities such as the mean energy and helicity are typically time-dependent. The effect of non-stationarity on the turbulent…
Compressible test-field method and its application to shear dynamos
Maarit J. Käpylä, Matthias Rheinhardt, Axel Brandenburg
In this study we present a compressible test-field method (CTFM) for computing effect and turbulent magnetic diffusivity tensors, as well as those relevant for mean ponderomoti…
Spectral characterisation of inertial particle clustering in turbulence
N. E. L. Haugen, A. Brandenburg, C. Sandin +1
Clustering of inertial particles is important for many types of astrophysical and geophysical turbulence, but it has been studied predominately for incompressible flows. Here we st…
Turbulent radiative diffusion and turbulent Newtonian cooling
Axel Brandenburg, Upasana Das
Radiation transport plays important roles in stellar atmospheres, but the effects of turbulence are being obscured by other effects such as stratification. Using radiative hydrodyn…
On the existence of shear-current effects in magnetized burgulence
Maarit J. Käpylä, Javier Álvarez Vizoso, Matthias Rheinhardt +2
The possibility of explaining shear flow dynamos by a magnetic shear-current (MSC) effect is examined via numerical simulations. Our primary diagnostics is the determination of the…
The nature of mean-field generation in three classes of optimal dynamos
Axel Brandenburg, Long Chen
In recent years, several optimal dynamos have been discovered. They minimize the magnetic energy dissipation or, equivalently, maximize the growth rate at a fixed magnetic Reynolds…
