Numerical study of static pressure on the sonochemistry characteristics of the gas bubble under acoustic excitation

open access: yesOpen Physics, 2023
The extreme environment formed during bubble collapse can cause a series of chemical reactions inside the bubble, and multiple products (i.e., ˙OH, H˙, O, H2, and HO2˙, etc.) are produced, which is called sonochemistry. In this study, a new model is used

Acoustic cavitation and sonochemistry [PDF]

open access: yes, 2013
Sonochemistry is the use of cavitation for achieving a chemical conversion. When microbubbles are driven in the nonlinear regime, localized extreme temperatures (up to 10000 K) and pressures (up to 1000 bar) can be reached upon collapse, the surrounding ...
