In the early years of PHOENICS, the energy equation was solved
with enthalpy as the dependent variable; temperature was
treated as an auxiliary variable, the values of which were to
be deduced from those of enthalpy by way of the specific heat
capacity of the fluid.
However, this was troublesome when so-called 'conjugate heat
transfer' problems had to be solved with heat-conducting
solid materials immersed in fluids; for each material could
have a different specific heat.
This library case was introduced at the time at which solving
for temperature directly was introduced, this being achieved
by use of the material-marker variable PRPS, wht value of
which at each point indicated what material, and therefore
what specific heat, was to be used there.
The steady flow in a cavity with one moving wall is modelled.
The stationary walls are at one temperature, and the wall
moving with a constant velocity is adiabatic
Within the cavity is a heated block of steel. The fluid is
water.

The geometry is as for case 921, but the north wall no longer
moves. Instead, the motion is induced by allowing for the
effect of buoyancy, by way of the Boussinesq approximation.
The PHOTON USE macro of case 921 can be activated by issuing the
command 'use Q1EAR'; but not 'use Q1'. The reason is that the
date of case 921 have been brought in by way of the compact
#$921 command above.

This case is like case 922; but the fluid is glycerine
