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.
Keywords: numerical simulation, EM induction furnace, EM levitation, twophase
turbulent flow, free surface.
