Wave Heating of Coronal Loops with Steady Flows
Abstract
We derive a general dispersion relation for hydromagnetic waves in inhomogeneous coronal loops with steady plasma flows. We model static loops by assuming the equilibrium magnetic and plasma configuration of solar coronal loops as slab geometry, with the z-axis of the slab along the uniform background magnetic field. We assume a density stratification perpendicular to the direction of the background magnetic field. Here we evaluate the extent to which hydromagnetic waves can be collisionally dissipated, that is, their dissipation by viscosity and heat conduction in the coronal loops when invoking steady flow, and we compare the results with the minimum that is required to satisfy the optically thin radiative cooling rate.
