On the dynamics and breakup of a bubble immersed in a turbulent flow [PDF]
, 2011 Experimental investigations of the dynamics of a deformable bubble rising in a uniform turbulent flow are reported. The turbulence is characterized by fast PIV.

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 ...

Observations and scaling of travelling bubble cavitation [PDF]
, 1995 Recent observations of growing and collapsing bubbles in flows over axisymmetric headforms have revealed the complexity of the ‘micro-fluid-mechanics’ associated with these bubbles (van der Meulen & van Renesse 1989; Briancon-Marjollet et al.

Simple improvements to classical bubble nucleation models [PDF]
, 2015 We revisit classical nucleation theory (CNT) for the homogeneous bubble nucleation rate and improve the classical formula using a new prefactor in the nucleation rate.

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.

Bubble Lift-off Size in Forced Convective Subcooled Boiling Flow [PDF]
, 2005 Forced convective subcooled boiling flow experiments were conducted in a BWR-scaled vertical upward annular channel. Water was used as the testing fluid, and the tests were performed at atmospheric pressure.

Numerical simulations of non-spherical bubble collapse [PDF]
, 2009 A high-order accurate shock- and interface-capturing scheme is used to simulate the collapse of a gas bubble in water. In order to better understand the damage caused by collapsing bubbles, the dynamics of the shock-induced and Rayleigh collapse of a ...
