Ultrasonic Measurement of Two-Dimensional Liquid Velocity Profile Using Two-Element Transducer

The flow field or multidimensional velocity distribution of the coolant in fuel rod bundles reactor core pressurized water reactors (PWRs) is an important parameter that revealed through experimental investigations. This paper presents two-dimensional (2D) profile measurement using a two-element ultrasonic transducer with both elements acting as transceiver. size minimized for compactness, leading to narrow sound appropriate applications bundle flow. Furthermore, transducer’s pressure evaluated via simulations and measurements. In order confirm ability profiler (UVP) transducer, conducted turbulent horizontal pipe 2D vector obtained, then swirling conducted. axial radial plane obtained utilizing UVP measurement. Lastly, derive area demonstrated.
