Steady Flows in Magnetic Arcades A Class of Exact Mhd Solutions

Research output: Contribution to journal › Article › peer-review

Abstract

A class of exact solutions to the steady, two-dimensional magnetohydrodynamic equations in a cartesian geometry is presented. The method developed by Tsinganos (1981, 1982) is employed. These solutions may mode! siphon flow in magnetic arcades, the flow being driven by pressure differences between the footpoints. The basic result is that the presence of inertial forces causes the arcade to rise in comparison to the static case. Eventually, the arcade may be caused to erupt by continuing to increase the magnitude of inertial forces.
