“…More recent application of PIV within novel fluid dynamics contexts includes hemodynamics in the Carotid Artery [10], fuel cell design [11], and breath flows relating to COVID-19 transmission [12]. Further, PIV based techniques are now used within non-traditional fluid dynamics contexts, to include estimating insect traffic [13], identifying soil-pile interactions [14], and tracking the movement of geophysical flows such as avalanches [15].…”
