TALK=T;RUN(1,1) DISPLAY This case simulates the steady flow of a two-phase mixture in a 2-D duct, with heated walls. The mixture has uniform composition at inlet; but the distribution changes with distance downstream, for two reasons, namely:- 1. the denser fluid moves to the outside of the bends; and 2. dense fluid changes into light, through boiling near the heated walls. You may determine whether the activate both effects by your answer the following question. This Q1 contains PHOTON USE commands.
