  • Cavitation is the formation and then implosion of cavities in a liquid - i.e. small liquid-free zones (“bubbles") - that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities where the pressure is relatively low.
