Sonochemistry and bubble dynamics
Ultrasonics 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.

Dynamics of a high-Reynolds-number bubble rising within a thin gap [PDF]
, 2012 We report an experimental analysis of path and shape oscillations of an air bubble of diameter d rising in water at high Reynolds number in a vertical Hele-Shaw cell of width h.

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 ...

Bubble formation at a flexible orifice with liquid cross-flow [PDF]
, 2004 In waste water treatment, biological processes for denitrification and nitrification are performed using oxidation ditches. In these reactors, the mixing and the aeration functions are dissociated: a bubble cloud is generated from flexible membrane ...

Numerical simulation of bubble generation in a T-junction [PDF]
, 2012 We present a numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM. Numerical simulations were carried out for different flow conditions, giving rise to results on the behavior of bubble ...

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 ...

Homogeneous swarm of high-Reynolds-number bubbles rising within a thin gap. Part 1: Bubble dynamics [PDF]
, 2012 The spatial distribution, the velocity statistics and the dispersion of the gas phase have been investigated experimentally in a homogeneous swarm of bubbles confined within a thin gap. In the considered flow regime, the bubbles rise on oscillatory paths

Dynamics of bubble growth and detachment from rigid and flexible orifices [PDF]
, 2003 The objective of this paper is to understand how and why the orifice nature (rigid or flexible) governs the bubble generation. The differences in orifice nature and properties have strong consequences on the bubbles generated.

Bubble growth in a two-dimensional viscoelastic foam [PDF]
, 2006 The effects of viscoelasticity on the expansion of gas bubbles arranged in a hexagonal array in a polymeric fluid are investigated. The expansion is driven by the diffusion of a soluble gas from the liquid phase, and the rate of expansion is controlled ...
