Sustained turbulence and magnetic energy in non-rotating shear flows (1701.03531v2)
Published 12 Jan 2017 in physics.plasm-ph, astro-ph.GA, and astro-ph.SR
Abstract: From numerical simulations, we show that non-rotating magnetohydrodynamic shear flows are unstable to finite amplitude velocity perturbations and become turbulent, leading to the growth and sustenance of magnetic energy, including large scale fields. This supports the concept that sustained magnetic energy from turbulence is independent of the driving mechanism for large enough magnetic Reynolds numbers.
