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

摘要

Heat transfer problem in he strand during continuous acting is considered in the paper. Steady sate temperature field in a coordinate system attached to the mould has been analyzed. Phase change is assumed to take place at constant temperature. The nonlinearly in this problem is caused by the unknown location of the solid-liquid interface. To determine both, this location and the resulting temperature field in the strand, a novel BEM front algorithm has been developed. Numerical examples like one-dimension (1D) phase change benchmark (modeled as two-dimensional (2D)) and several 2D problems of continuous casting of copper are included and discussed.
