dc.description.abstractThedynamics of solid particles in turbulent flows are crucial for industrial applications such as transport of mining slurries, where particle trajectories are essential for predicting erosive wear. This study evaluates the use of ultrasound particle image velocimetry (UPIV) to measure the velocity field of glass beads (250–300 µm; 1, 2, 3 wt.%) in a controlled turbulent setting (slurry pot, Stokes number 1.21–5.66, Reynolds number 1.75×105) validating the results against optical PIV measurements. A line density correction is developed to address the errors caused by electronic sweeping and transducer artifacts, both inherent to UPIV. The standard error in transversal velocity is reduced by 21.6%. Although UPIV operates at a lower frame rate (335 fps), wavelet analysis validates its effectiveness in capturing flow structures relevant to erosive wear. These findings highlight UPIV’s potential to advance the study of flow dynamics in opaque media.
