Abstract
In this work, the flow of Wood's metal alloy and its free surface dynamics in an external electromagnetic field of an axially symmetric induction crucible furnace is studied. Applying the ANSYS modelling features, a 2D model for phase surface dynamics caused by inductor switch on is developed and current and frequency affect on the dynamics is discussed. The model is verified by free surface steady state result comparison to other models and appropriate experimental data. On the basis of the obtained results the analysis of steady state free surface dependence on the inductor current and frequency is performed. Figs 10, Refs 5.
