The surface temperature at the left side is 1000K. The surface at the right side has a heat-transfer coefficient of 10W/m^2/K to an external temperature of 293K. The surface temperature of the right side, Tw, is calculated. The PHOENICS solution can be compared with the analytical solution which shows that TS=968K , and the external heat transfer rate=6.750kW ENDDIS ************************************************************ Group 1.
