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 ...

A Modified Phase-Transition Model for Multi-Oscillations of Spark-Generated Bubbles
Inventions, 2023 The main composition within a spark-generated bubble primarily consists of vapor, accompanied by a minor presence of noncondensable gases. The phase transition exerts a substantial influence on bubble dynamics throughout various stages, a facet that has ...

Acta Physica Sinica, 2008 The fluid is assumed to be inviscid and incompressible and the flow irrotational. The three_dimensional numerical model is established to simulate the interaction of multiple bubbles and the fast Fourier transform on multipoles (FFTM) method is combined with the higher order boundary method (BEM) to study the physics of multiple bubble dynamics.

Dynamics of false-vacuum bubbles [PDF]
Physical Review D, 1987 The possibility of localized inflation is investigated by calculating the dynamics of a spherically symmetric region of false vacuum which is separated by a domain wall from an infinite region of true vacuum. For a range of initial conditions, the false-vacuum region will undergo inflation.

Investigating Bubble Frequency Changes in Pool Boiling in Pure Solutions and on a Stainless Steel Cylinder [PDF]
Chemical Process Design, 2022 Bubble dynamics is the most important sub-phenomenon, which basically affects the nucleate pool boiling heat transfer coefficient which includes bubble departure frequency, bubble diameter and nucleation site density.

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.

Cavitation And Bubble Dynamics [PDF]
, 1995 Abstract The book describes and explains the fundamental physical processes involved in bubbly dynamics and the phenomenon of cavitation. The study of cavitation and bubbly flow applies to many areas of interest; from valve damage in hydroelectric equipment, ship propellors and internal combustion engines to the performance of ...
