Ultrasonics Sonochemistry, 2023 Bubble dynamics is important in flow boiling of minichannel, and ultrasonic field effects bubble behaviors. However, flow boiling bubble movements in minichannels under ultrasonic field have received little research attention and are still poorly ...

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.

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.

Numerical simulation of bubble dispersion in turbulent Taylor-Couette flow [PDF]
, 2014 We investigate bubble dispersion in turbulent Taylor-Couette flow. The aim of this study is to describe the main mechanisms yielding preferential bubble accumulation in near-wall structures of the flow.

Fluids, 2023 The jet impact from a collapsing bubble is an important mechanism of structural damage in underwater explosions and cavitation erosion. The Boundary Integral Method (BIM) is widely used to simulate nonspherical bubble dynamic behaviors due to its high ...

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices [PDF]
, 2004 The influence of liquid surface tension on the bubble formation from both rigid and flexible orifice has been investigated. The liquid phases under test are aqueous solutions with butanol or surfactants (cationic, non-ionic and anionic); static and ...

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.

Multiple changes in persistence vs. explosive behaviour: the Dotcom bubble [PDF]
, 2012 Based on a method developed by Leybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the NASDAQ stocks.
