Numerous experiments suggest that bubble formation in water is initiated by preexisting gas nuclei. This is unexpected since gas phases larger than the order of 1 μm in radius ought to rise to the surface of a standing liquid, whereas smaller ones should dissolve rapidly via the outward diffusion of gas that results from surface tension. Several mechanisms for stabilizing gas nuclei have been proposed, but in each case there is experimental evidence to the contrary. In this article, a model is…

Cavitation inception from bubble nuclei
These results suggest that cavitation nuclei in equilibrium are gaseous voids in the water, stabilized by a skin which allows diffusion balance between gas inside the void and gas in solution in the surrounding liquid.
Determination of the radii of gas cavitation nuclei by filtering gelatin
We report an experiment in which the size distributions of the entities which initiate bubble formation in supersaturated gelatin are systematically altered by passing test samples through Nuclepore
Nucleation and stabilization of microbubbles in liquids
An important aspect of the processes of cavitation and boiling is the concept of a nucleus that acts as a preferential site for the inception of these events. It is commonly thought that except for
Stabilized bubbles in the body: pressure-radius relationships and the limits to stabilization.
The present goals are to develop the idea that there are limits to the stabilization and to provide a conceptual framework for comparison of bubbles stabilized by different mechanisms.
Bubble nucleation in aqueous media: implications for diving physiology
A cavitation model developed at the University of Hawaii in which spherical gas nuclei are stabilized by surface-active skins of varying gas permeability provides a precise quantitative description of bubble counts made in supersaturated gelatin, and it accurately predicts levels of incidence for decompression sickness in several animal species.

An independent derivation of this model for microbubble nuclei is obtained by applying thermodynamic methods formulated recently to describe strongly curved amphiphilic interfaces and provides additional information on the mechanical and thermodynamic properties of interfaces in general.


Onset of Ultrasonic Cavitation in Tap Water
The conditions influencing the onset of acoustically‐induced cavitation in tap water have been investigated, with special attention to the role of air‐filled nuclei. Cavitation was induced by
