In the research area of magnetohydrodynamics the pulsed-wave ultrasound Doppler velocimetry (UDV) is a worthwhile measurement technique for flow field investigations of liquid metal flows. Several UDV instruments are available on the market. However, their capability for twodimensional mapping of flows is highly limited due to restricted number of scanning elements and low temporal resolution. Hence, we present an ultrasound Doppler velocimeter based on the application of ultrasound transducer arrays which allows measuring the in-plane...
