Cross-helicity effects and turbulent transport in magnetohydrodynamic flow
Cross-helicity effects turbulent transport magnetohydrodynamic

2011/9/28
In the presence of large-scale vortical motions and/or magnetic-field strains, the turbulent cross helicity (velocity--magnetic-field correlation in fluctuations) may contribute to the turbulent elect...

We present a numerical extension to the analytical propagation model introduced in Hein and Spanier (2008) to describe the leptonic population in the galactic disc. The model is used to derive a possi...

In this paper we present a new five particle species hybrid model for calculating cosmic ray particle transport and acceleration in a dynamic heliospheric environment. In particular the effects of sol...

We reexamine arguments advanced by Hayashi & Matsuda
(2001), who claim that several simple, physically motivated derivations
based on mean free path theory for calculating the viscous torque in a
