This video captures the intricate dynamics of cavitation, focusing on the breakup of a cavity from the throat and its transformation into clouds of vapor. The process is driven by various instability mechanisms, including the re-entrant jet and condensation shock. Through high-speed imaging, the video reveals the complex behavior of cavitation, showcasing how small-scale instabilities evolve into large-scale structures. This exploration provides insights into the fundamental mechanisms behind cavitation cloud shedding and the transitions that occur due to fluid-structure interactions.
