New possibilities for velocity measurements and model experiments in liquid metal processing

Potential difference probes and ultrasound have been employed to investigate liquid metal flows in cylindrical containers.
The fluid motion was driven by either a rotating or a pulsating magnetic field. Experimental results containing flow mapping and scaling of mean velocities for very small driving forces will be presented. We report on our new MULTIMAG facility which allows for almost any combination of rotating, traveling, pulsating and d.c. magnetic fields in extended geometries for industrially relevant regimes.
