Control of liquid metal free surface waves by a magnetic field in the processing of materials

    Research output: Contribution to journalConference articlepeer-review

    Abstract

    The paper deals with one particular example of Electromagnetic Processing of Materials (EPM) as an efficient and environmentally friendly technology response to the increase in energy consumption driven by the high demand for high-grade materials free from contamination and external agents. EPM is a nonintrusive technology that allows efficient manipulation, monitoring, and control of conducting materials, such as liquid metals, semiconductors, molten salts, and electrolytes. This paper focuses on stabilizing or damping the unwanted waves on the surface of liquid metal in industrial processing, such as strip casting and coating with a uniform and constant magnetic field. The study includes the orientation of the applied magnetic field relative to the free surface, the effects of the depth of the fluid layer, viscosity, and surface tension.
