Abstract

On account of ANSYS Classic, ANSYS CFX and ANSYS Fluent external coupling a numerical model for EM induced flow and free surface dynamics of melt in induction furnaces is developed. The model is adjusted for the case of EM levitation and extended on 3D with application of LES turbulence. Calculated steady state free surface shapes are compared to other models and experimental measurements in induction furnaces and EM levitation melting setup, predicted free surface dynamics is compared to analytical estimation of free surface oscillation period. The model accuracy is approved. The model is applied for tailoring EM levitation furnace design to meet conditions for levitation of greater charge weight. Numerical results reveal difficulties that must be considered in case of EM levitation in horizontal orthogonal EM field and appear to be in a good agreement with experiment.
