Effects of medium viscoelasticity on bubble collapse strength of interacting polydisperse bubbles

open access: yesUltrasonics Sonochemistry, 2023
Due to its physical and/or chemical effects, acoustic cavitation plays a crucial role in various emerging applications ranging from advanced materials to biomedicine. The cavitation bubbles usually undergo oscillatory dynamics and violent collapse within

Interactions between a central bubble and a surrounding bubble cluster

open access: yesTheoretical and Applied Mechanics Letters, 2023
The interaction of multiple bubbles is a complex physical problem. A simplified case of multiple bubbles is studied theoretically with a bubble located at the center of a circular bubble cluster.

Investigation of Cavitation Bubble Dynamics Considering Pressure Fluctuation Induced by Slap Forces

open access: yesMathematics, 2021
Cavitation erosion is induced by the penetrating pressure from implosion of cavitation bubbles nearby solid boundary. The bubble evolution and the subsequent collapse pressure are especially important to evaluate the erosion degradation of solid boundary

Sonochemistry and bubble dynamics

open access: yesUltrasonics Sonochemistry, 2015
The details of bubble behaviour in chemically active cavitation are still not sufficiently well understood. Here we report on experimental high-speed observations of acoustically driven single-bubble and few-bubble systems with the aim of clarification of the connection of their dynamics with chemical activity.

Influence of physical parameters on the collapse of a spherical bubble

open access: yesTheoretical and Applied Mechanics Letters, 2022
This paper examines the influence of physical parameters on the collapse dynamics of a spherical bubble filled with diatomic gas (κ=7/5). The problem is formulated by the Rayleigh–Plesset dynamical equation, whose numerical solutions are carried out by ...
