Key words instabilities – magnetic fields – magnetohydrodynamics (MHD) – turbulence In this study we provide the first numerical demonstration of the effects of turbulence on the mean Lorentz force and the resulting formation of large-scale magnetic structures. Using three-dimensional direct numerical simulations (DNS) of forced turbulence we show that an imposed mean magnetic field leads to a ...

Key words galaxies: magnetic fields – magnetohydrodynamics (MHD) – turbulence We summarize the current state of the long term discussion about the saturation mechanisms associated with rapid growth of small-scale magnetic field, that operate in large-scale galactic dynamos, and related problems with magnetic helicity conservation. Our general conclusion is that, taking into account magnetic hel...

متن کاملH . W . Yorke ( Pasadena ) Founded by H . C . Schumacher in 1821
The decay of kinetic helicity is studied in numerical models of forced turbulence using either an externally imposed forcing function as an inhomogeneous term in the equations or, alternatively, a term linear in the velocity giving rise to a linear instability. The externally imposed forcing function injects energy at the largest scales, giving rise to a turbulent inertial range with nearly con...

TO THE EDITOR: The Letter to the Editor by Schumacher et al. (10) is well formulated but with no relevance for our studies (5, 8, 11) in which we aimed to pinpoint physiological factors that could lead to increases in exercise performance after altitude training. We specifically designed our study to separate the potential effects of hematological adaptations to hypoxia from other hypoxia-induc...
