Abstract

In this paper, a heat transfer problem of continuous casting is solved by two BEM approaches, i.e. front tracking and fixed grid with dual reciprocity. Both techniques are compared and critically evaluated by solving two numerical examples consisting of determining the temperature field and location of phase change front. Good accuracy has been observed. 1 Introduction Transport phenomena encountered in solid-liquid phase change sys- tems are of great importance in fundamental research as well as in many branches of engineering. Extensive survey of the discipline can be found in many references, e.g. [1], [2]. Since geometrical complex- ity and nonlinearities practically do not allow to obtain analytical solutions, numerical techniques are almost e
