Abstract: | A two dimensional model of the transition region and the lower corona, based on the idea that the magnetic flux is strongly
concentrated at the boundaries of the supergranular convection cells, has been proposed by Gabriel in 1976. The plasma moves
along the open magnetic field lines, which define the the so-called "funnel," and eventually builds up the solar wind.
Based on a two dimensional funnel model we investigate the stationary plasma flow at its central line, taking heat conduction,
radiative losses, and a heating function into account. The derived height profiles of the plasma properties within the funnel
are presented.
