The aim of this article is to demonstrate the capability of the software for predicting free-surface motion and internal fluid flow in an electromagnetically levitated sample of liquid metal. Multiphysics solutions which demonstrate the usefulness of Comsol as a powerful MHD simulation tool have been generated to two industrial problems using the ALE moving-mesh module in combination with the Navier-Stokes and Maxwell solvers.
The first problem concerns the thermo-physical property measurement of reactive molten materials. The second problem, having relevance to continuous casting of metal ingots in a cold crucible, considers the transient free-surface motion of a semi-levitated volume of metal when its shape is confined by the field of a surrounding solenoid.
