Acceleration-induced cavitation and surrounding pressure in a short liquid column

Cavitation emerges due to sudden acceleration of a liquid (e.g., an impact to the liquid-filled container, the valve operation in a pipe system) and can cause severe damages on surrounding structures. This presentation mainly focuses on the dynamics of acceleration-induced cavitation bubbles and surrounding liquid pressure in a liquid-filled container. We firstly show the criteria for the onset of the acceleration-induced cavitation in a short liquid column. We then investigate the interaction between the dynamics of cavitation bubbles and the pressure field using a high-speed camera and a pressure sensor. Finally, we discuss the impulsive force upon the collapse of cavitation bubbles.
