The induction channel furnace (ICF) is widely used in industry for melting, holding and casting of metals. However, up to now there are still open questions regarding the heat and mass exchange in the inductor channel itself and between the channel and the bath. In this paper, the melt flow velocities and the temperature distribution in the melt of the ICF are modelled using a 3D electromagnetic model and a 3D transient LES approach. The numerical results are verified by temperature and velocity distributions measured in an experimental full-scale inductor channel furnace operating with Woods metal as a low temperature model melt.
