Comparison of flow measurements in a cold liquid metal model for continuous casting of steel carried out by an arrangement of individual US transducers and a linear US array

Flow measurements by means of the Ultrasound Doppler Velocimetry (UDV) have been carried out in a cold liquid metal mockup experiment to model the continuous casting process of steel. The setup was realized in the mini-LIMMCAST facility and represents a 1:3 scale model of a typical industrial bloom caster. An arrangement of ten individual ultrasonic sensors attached to a commercial system and an academic UDV system with linear ultrasound array was mounted along the mold to capture the velocity distribution near the meniscus and the submerged entry nozzle (SEN). The results obtained by the two measurement systems are compared and show the superiority of the academic system due to its higher spatial resolution.
