The Hydrodynamic Cavitation Manifestation in Small Chips [PDF]
IEEE Access, 2021 Abstract Cavitation is a phase change phenomenon created by the static pressure reduction of a liquid medium at a constant temperature. This process has been considered as a disadvantageous mechanism in most turbomachinery systems, however, its potential in releasing energy at the bubble collapse stage has received lots of attention in recent ...

Hydrodynamic cavitation for sonochemical effects
Ultrasonics Sonochemistry, 1999 A comparative study of hydrodynamic and acoustic cavitation has been made on the basis of numerical solutions of the Rayleigh-Plesset equation. The bubble/cavity behaviour has been studied under both acoustic and hydrodynamic cavitation conditions. The effect of varying pressure fields on the collapse of the cavity (sinusoidal for acoustic and linear ...
