DISPLAY
The system simulated is a horizontal cylindrical heat
exchanger. Water enters the heat exchanger at the side,
and is directed tangentially. It leaves through a vent
at the top of the cylinder. Because of symmetry, only a
180 degree sector is considered as the domain of
integration in cylindrical-polar coordinates.
In its passage through the heat exchanger, the water is
heated by a tube bank which supplies a constant heat flux
in to the water. The blockage to flow caused by the
presence of the tube bank is represented by means of
porosity factors set by the command CONPOR. Momentum sinks
representing the resistive effect of the tubes have not
been included.
The flow pattern is governed chiefly by buoyancy effects,
with the result that for some heating rates, unexpected
flow patterns are produced which cause hot spots to appear.
The flow is laminar throughout.
