TALK=T;RUN(1,1) DISPLAY The case considered is 2d transient turbulent fluid flow and heat transfer of liquid steel (melt) in a ladle. This case has been studied numerically by Chakraborty and Sahai (Metall. Trans. B, Vol.23B, p135, 1992). The cylindrical ladle is 3.35m in diameter, and the melt depth is 4m, and the holding period before release of the melt into the mold is 20 minutes. The melt is taken to be stagnant and isothermal at the start of the holding period. The free surface is presumed flat, and heat loss rates are prescribed at both walls and the free surface. Convection currents are set up in the melt due to buoyancy forces resulting from the cooling of the melt with time. After about 5 or 10 minutes, it is expected that a clockwise overall recirculation pattern will be established within the melt.
