Power consumption of skull melting, Part II: Numerical calculation of the shape of the molten zone and comparison with experiment

A mathematical model for the numerical calculation of the shape of the molten zone during high frequency (HF) inductive Skull melting of ceramic materials in the cold crucible is presented. The mutual interaction between the molten zone and the HF electromagnetic field of the inductor is considered by an axisymmetric model because of the good electromagnetic transparency of the slitted crucible wall (see part I). By means of the developed corresponding Finite-Element program package the shape of the molten zone and corresponding power consumption of the system are calculated. The dependence of the shape of the molten zone on system parameters is analyzed numerically and compared with experimental data. Additionally, some further investigations on stability of the molten zone are performed.
