Cavitation Strength, Acoustic Nonlinearity, and Gas Bubble Distribution in Water
Fluids, 2023 The acoustic properties of real liquids are largely related to the phase inclusions contained in them, of which gas bubbles are the most common. The aim of the work was to find the relationship between the nonlinear acoustic parameter and the cavitation ...

Inner surface peening for long and narrow helical pipe using acoustic cavitation
Materials & Design, 2023 The inner surface peening of helical pipes is highly challenging due to the inaccessibility of the inner surface. To the end, we propose to peen the inner surface by introducing acoustic cavitation inside the pipe. We also provide a theory to account for

Acoustic surface cavitation [PDF]
, 2011 Merely the presence of compressible entities, known as bubbles, greatly enriches the physical phenomena encountered when introducing ultrasound in a liquid. Mediated by the response of these bubbles, the otherwise diffuse and relatively low energy density of the acoustic field can induce strong, localized liquid motion, high internal temperatures and ...
