Abstract
We present a hydrodynamic model of stationary siphon flows in a semicircular solar coronai loop. The model takes into account the effects of gravity, thermal conduction, radiative losses and a phenomenological heating term.
The model has been designed to provide a tool for insight into coronai loop physics and to help interpretation of the observations of new UV and X-ray instruments.
We derive scaling laws for subsonic flows in coronai loops which extend those of Rosner Tucker and Vaiana (1978) and of Serio et al. (1981) to the siphon flows. We explore thoroughly the space of solutions and identify four classes of solutions.
Finally, we explore the conditions for the presence of stationary shocks in critical and supersonic siphon flows in coronal loops.
