TALK=T;RUN(1,1) DISPLAY 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.
