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.

Hydrodynamics, acoustics and scaling of traveling bubble cavitation [PDF]
, 1994 Recent observations of the geometries of growing and collapsing bubbles over axisymmetric headforms have revealed the complexity of the "microfluidmechanics" associated with these flows (Hamilton et al., 1982, Briancon Marjollet and Franc, 1990, Ceccio ...

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 ...

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.

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 ...

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 ...

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.

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 ...
