Experimental investigation of rotating liquid metal flows

Several experiments considering electromagnetically driven liquid metal flows in cylindrical vessels will be presented. The focus of the experiments is ranging from meteorological and geophysical effects like inertial waves and tornado-like vortices. Besides, flows with industrial relevance like the mixing of floating particles into a metallic melt or the mixing enhancement in gas stirred ladles is considered. Different ultrasound-based measurement techniques were used in these experiments whereby the ultrasound-Doppler-velocimetry (UDV) is the most important one.
