Heat transfer analysis of the continuous casting process by the front tracking BEM

Heat transfer problem in the strand during continuous casting is considered in the paper. Steady state temperature field in a coordinate system attach ed to the mould has been analyzed. Phase change is assumed to take place at constant temperature. The nonlinearity in this problem is caused by the un known location of the solid-liquid interface. To determine both, this locat ion and the resulting temperature field in the strand, a novel BEM front tr acking algorithm has been developed. Numerical examples like one-dimensional (1D) phase change benchmark (modele d as two-dimensional (2D)) and several 2D problems of continuous casting of copper are included and discussed.
