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 molt en zone during high frequency (HF) inductive Skull melting of ceramic mater ials 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 o f the slitted crucible wall (see part I). By means of the developed corresp onding Finite-Element program package the shape of the molten zone and corr esponding power consumption of the system are calculated. The dependence of the shape of the molten zone on system parameters is analysed numerically and compared with experimental data. Additionally, some further investigati ons on stability of the molten zone are performed.
