TLDR
In this article, approximate solutions for the rate of solution by diffusion of a gas bubble in an undersaturated liquid-gas solution are presented, with the neglect of the translational motion of the bubble.
Abstract: 
With the neglect of the translational motion of the bubble, approximate solutions may be found for the rate of solution by diffusion of a gas bubble in an undersaturated liquid‐gas solution; approximate solutions are also presented for the rate of growth of a bubble in an oversaturated liquid‐gas solution. The effect of surface tension on the diffusion process is also considered.

Reflections on cavitation nuclei in water

Knud Aage Mørch
- 10 Jul 2007 - 
TL;DR: The origin of cavitation bubbles, cavitation nuclei, has been a subject of debate since the early years of the cavitation research as discussed by the authors, and a representative selection of experimental investigations of Cavitation inception and the tensile strength of water is presented in this paper.

Theory of gas bubble dynamics in oscillating pressure fields

Milton S. Plesset, +1 more
- 01 Nov 1960 - 
TL;DR: In this article, the behavior of a permanent gas bubble in a liquid with an oscillating pressure field is analyzed with a linearized theory, and the assumption that conditions within the bubble are uniform is made that the thermodynamic relations found are as expected; i.e., at low frequencies the bubble behaves isothermally and at high frequencies the behavior becomes adiabatic.

Novel preparation techniques for controlling microbubble uniformity: a comparison

Eleanor Stride, +1 more
- 12 May 2009 - 
TL;DR: The aim of the work described in this paper was to compare a conventional microbubble preparation technique, sonication, with two more recent methods: coaxial electrohydrodynamic atomisation and microfluidic (T-junction) processing, in terms of their ability to produce bubbles which are sufficiently small and stable for in vivo use, microbubbles uniformity, relative production rates and other practical and economic considerations.

Exposing nanobubble-like objects to a degassed environment.

R.P. Berkelaar, +5 more
- 18 Jun 2014 - 
TL;DR: After thorough investigation of the procedures and materials used during the experiments, it is found that the nanobubble-like objects were induced by the use of disposable needles in which PDMS contaminated the water.

Granular soils in rigid-wall permeameters: method for determining the degree of saturation

Robert P. Chapuis, +2 more
- 01 Feb 1989 - 
TL;DR: In this article, a simplified test to check a rigid-wall permeameter is proposed, based on the fact that for unsaturated conditions the hydraulic conductivity depends on which of two ways the water seeps in a given direction.

The Dynamics of Cavitation Bubbles

Milton S. Plesset
- 01 Sep 1949 - 
TL;DR: In this paper, three regimes of liquid flow over a body are defined, namely: (a) noncavitating flow, (b) cavitating flow with a relatively small number of cavitation bubbles in the field of flow, and (c) caviting flow with one large cavity about the body.
