Velocity measurements in metallic melts driven by AC magnetic fields in a square vessel

Model experiments are an important tool to understand the details of the flow structure and the transport properties of flows occurring in real-scale metallurgical facilities as well as to validate the multitude of numerical codes for flow simulation. The present study considers the electromagnetic stirring of a liquid metal by a rotating magnetic field (RMF). Measurements of the velocity field in a square column filled with the eutectic GaInSn have been carried out utilising the ultrasound Doppler velocimetry (UDV). In this paper the spatiotemporal properties of both the primary, swirling and the secondary flow arising from a sinusoidal modulation of the RMF will be presented.
