TALK=T;RUN(1,1)
DISPLAY
This run illustrates what happens when a fluid enters a duct
between two plane walls which are held at unequal temperatures.
Interesting parametric variations include: entry values of the
scalar variables; an additional boundary condition at the entry
section which would give the central region of the stream
a different set of values of the scalars; change to a flux
boundary condition on one of the walls; and the introduction of
temperature- dependent transport properties.
