For simplicity, a two dimensional geometry with a symmetry plane (Figure 4.3) was initially created assuming the collector is mounted flat on a roof.
The next fastest fluid motion is a layer along the upper glass cover, with the fluid dropping down into the cavity from the glass at the symmetry plane.
Heating of the base of the cavity by the long wave radiation from the absorber drives convection cells in the bottom with a rising plume up the symmetry plane.
Figure 4.27 shows that half of the geometry was simulated assuming a symmetry plane.
The velocity magnitude for a horizontal and a 40o inclined cavity are compared in Figure 4.35 along a line A-A in the symmetry plane.
