摘要：

Multiple configurations of synchronously rotating permanent magnet cylinders magnetized across the axes are proposed for liquidmetal stirring for homogenization as well as for pumping. Universal analytical model is used for an initial parameter analysis. Then experimental setups were built to perform physical modelling of the industrial applications, e.g. large-scale metallurgical furnaces. Velocity distribution in the liquid metal was measured using different methods: the Ultrasound Doppler anemometry and the potential difference probes. The study shows that the cylindrical permanent magnet setups can achieve up to 10 times higher energy efficiency compared to AC inductors and have potential of wide-range industrial application, e.g. can be used as stirrers for secondary aluminium furnaces with up to 50 cm thick walls.
