  DISPLAY


   IMMERSOL is used to simulate 2D radiative heat exchange in a
   duct flow with fixed wall temperatures. The flow may be laminar
   or turbulent. TEM1 and T3 are solved.

   Two solid plates (which may be of different materials and
   emissivities) are situated within the duct.

   The plates within the duct take up intermediate temperatures,
   being heated by radiation, but cooled by convection.
