PROPERTIES OF MAGNETIC HELICITY FLUX IN TURBULENT DYNAMOS
Abstract
We study the flux of small-scale magnetic helicity in simulations of driven statistically homogeneous magnetohydrodynamic turbulence in a periodic box with an imposed large-scale shear. The simulations show that in the regime of strong dynamo action the eddy-scale magnetic helicity flux has only two significant terms: advective motion driven by the large-scale velocity field and the Vishniac–Cho (VC) flux which moves helicity across the …
