Ultrasonic degassing is among the first potential applications of
acoustic cavitation in liquids.
In particular,
acoustic cavitation involves sending sound waves in the ultrasonic frequency range (>20 kHz) through a liquid medium.
It employs the
acoustic cavitation of microbubbles to enhance delivery of these large molecules.
The extraction process was assisted by sonication which is based on the sonochemical phenomenon associated with
acoustic cavitation [11] that helps the disruption of cell walls and facilitate the release of contents [12].
The sonochemical effect of the
acoustic cavitation in liquid causes a significant shortening between the range of chemical transformation and a continuous formation, growth and explosive collapse of the bubbles.
Acoustic cavitation produced by US exposure is believed to be the main physical mechanism caused by US exposure [20, 21].
As the bubbles violently collapse, they release tiny shock waves, a phenomenon called
acoustic cavitation.
Surface
acoustic cavitation understood via nanosecond electrochemistry.
It is generally accepted that ultrasonic irradiation affects chemical reactions through
acoustic cavitation in the reaction medium [1, 2].
This
acoustic cavitation can produce intra-bubble temperatures approaching l0,000[degrees]C.
Researchers knew then that collapsing bubbles could create high temperatures and pressures, a phenomenon known as
acoustic cavitation.
This type of cavitation is known as
acoustic cavitation, (Franc, 2004).
