Acoustic cavitation and bubble dynamics
Archives of Acoustics, 2008 Acoustic cavitation is investigated experimentally and theoretically starting with a single bubble in an acoustic field. The single bubble is trapped in an acoustic resonator and observed by high-speed imaging and acoustic measurements ...

Neural ‘Bubble’ Dynamics Revisited [PDF]
Cognitive Computation, 2013 In this paper, we revisit the work of John G Taylor on neural 'bubble' dynamics in two-dimensional neural field models. This builds on original work of Amari in a one-dimensional setting and makes use of the fact that mathematical treatments are much simpler when the firing rate function is chosen to be a Heaviside.

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

Ultrasonics Sonochemistry, 1997 The dynamics of cavitation bubbles on water is investigated for bubbles produced optically and acoustically. Single bubble dynamics is studied with laser produced bubbles and high speed photography with framing rates up to 20.8 million frames per second. Examples for jet formation and shock wave emission are given.

Influence of physical parameters on the collapse of a spherical bubble
Theoretical 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 ...
