Ultrasound cavitation refers to the formation, growth, and implosive collapse of bubbles in a liquid medium induced by ultrasound. These bubbles are microscopic voids that form when the tensile strength of a liquid is exceeded by the negative pressure generated by the sound waves. A common example is its application in medical treatments designed to target specific areas of the body.
The phenomenon holds significant importance due to its diverse applications, ranging from industrial cleaning and materials processing to therapeutic medicine. The implosion of cavitation bubbles generates intense localized heat and pressure, which can be harnessed for various purposes. Historically, observations of cavitation-related damage in hydraulic machinery led to its initial study, eventually paving the way for beneficial uses.
