Flow control in hot aggressive melts is a big challenge for metallurgical and glass technology applications. For instance, during the production of float glass, the glass melt solidifies on the top of a liquid tin bath. To achieve a spatially homogeneous glass thickness, both global and local control of the thermofluiddynamic transport phenomena in the tin bath are crucial. The concept a global flow control involves the coupling of the non‐contact electromagnetic flow rate measurement technique of Lorentz force velocimetry and the non‐contact flow driving technique of electromagnetic pumps based on rotating permanent magnets. The paper presents a model experiment using the low‐melting test melt GaInSn as well as numerical simulations using the commercial code FLUENT/MHD. (© 2011 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
