Bubble-bubble interaction: A potential source of cavitation noise

Physical Review E, 2009
The interaction between microbubbles through pressure pulses has been studied to show that it can be a source of cavitation noise. A recent report demonstrated that the acoustic noise generated by a shrimp originates from the collapse of a cavitation bubble produced when the shrimp closes its snapper claw.

Acceleration of Singlet Oxygen Evolution by Sonopiezoelectric Charge Transfer Over SrTiO3‐TiO2 Heterojunction for Selective Oxidation

Exploration, EarlyView.
A sonopiezo‐triggered singlet oxygen evolution system by S‐scheme SrTiO3‐TiO2 heterojunction was rationally designed to selectively remove electron‐rich pollutants from water. ABSTRACT Sonopiezo‐mediated heterogeneous catalysis is a promising technology for efficient removal of organic pollutants from wastewater. Nevertheless, it is challenging in real

Mass transfer of acoustic cavitation bubbles in multi-bubble environment

Ultrasonics Sonochemistry
The mass transfer around acoustic cavitation in a multi-bubble environment was numerically studied. To model the multi-bubble environment, several bubbles were placed at the vertices of the polyhedron, and one bubble was placed at the center, and then an ultrasonic pressure wave with a frequency of 20 kHz was imposed along the simulation boundary box ...

Cavitation erosion from single acoustically driven bubbles

Ultrasonics Sonochemistry
Acoustic cavitation is achieved by exciting mechanical vibrations at ultrasonic frequencies, which in turn cause the formation of bubble clouds, followed by flows and emulsification.

A derivation of the stable cavitation threshold accounting for bubble-bubble interactions

Ultrasonics Sonochemistry, 2017
The subharmonic emission of sound coming from the nonlinear response of a bubble population is the most used indicator for stable cavitation. When driven at twice their resonance frequency, bubbles can exhibit subharmonic spherical oscillations if the acoustic pressure amplitude exceeds a threshold value.
