Electromagnetic Processing from AC to DC Field and Multiphysics Modeling: a Way for Process Innovation
Examples of Electromagnetic processes are presented: (1) cold crucible, (2) electromagnetic pump, (3) DC electromagnetic brake. A combined approach by using multiphysics modeling with Comsol and experimental validation is used in order to give some guidelines for process improvement and integration at industrial scale. A time-dependent 2D or 3D multiphysics electromagnetic fluid mechanics coupled numerical model including an ALE deformed mesh technique was set up. New design of cold crucible with improved energetic efficiency was defined. MHD effects resulting from a strong coupling between fluid flow and electromagnetics is evaluated in a large annular linear pump for nuclear applications. The control of zinc coating thickness by DC magnetic field resulting from braking of a liquid driven by an upcoming strip was demonstrated.
