ABSTRACT

The experimental and numerical investigations of the turbulent melt flow are carried out in various laboratory- and industrial-sized induction furnaces, like induction crucible furnace and induction furnace with cold crucible (IFCC). The results of the transient 3D LES simulation of the turbulent melt flow revealed the large-scale periodic flow instabilities and the temperature distribution in the melt, which both are in good agreement with the expectations based on the data from the experiments. The studies, presented in this paper, contain the numerical simulation of turbulent melt flow of experimental and industrial-sized induction furnaces and demonstrate the possibility of using the three-dimensional transient LES approach for successful simulation of heat and mass transfer processes in metallurgical applications.
