n: the formation and collapse of vapour gas-filled cavities that result from a sudden decrease and increase of pressure. Cavitation can cause mechanical damage to adjacent surfaces in meters, valves, pumps, and pipes at locations where flowing liquid encounters a restriction or change in direction.

the creating of a high speed, very low pressure vapor bubble that quickly and violently collapses. Very detrimental to surfaces in the near proximity. Often seen in severe turbulent flow.

n: The pressure of fluid decreases below saturated vapor pressure and forms jet with numbers of air bubble when the fluid passes through special nozzle. The air bubble forms domestic high pressure when striking the solid border.
