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. / /| Wall / / | at temp---/ / | T1 / / | / / | | |Wall | Fixed | ^ |at | mass, |/ |temp | momentum, / |T2 | enthalpy /| ^ | / and conc- |/ | / ^ entration / | / /z fluxes /| ^ | / / |/ |/ / x---> ENDDIS ************************************************************ Group 1.
