Cavitation
FORMATION AND THEN IMMEDIATE IMPLOSION OF CAVITIES IN A LIQUID
Sonic cavitation; Cavitator; Cavitation inception; Cavitate; Cavitation erosion
Cavitation is a phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. When subjected to higher pressure, these cavities, called "bubbles" or "voids", collapse and can generate shock waves that may damage machinery.
