The problem of determining the position of the metal in levitation melting

Abstract

The correctness of using the moving mesh, which is the physical interface of the Comsol Multiphysics, to determine the position of the workpiece relative to the inductor during levitation melting is analyzed. The problem deals with transient modes of efforts, coordinate, velocity. Transient processes are described by ordinary differential equations. This model provides the opportunity to predict the maximum weight of the melting workpiece, the electromagnetic and energy characteristics, depending on the mass of the workpiece. The results are compared between the hydrodynamic calculation of the melted metal with positioning and the arbitrarily given coordinate.
