Influence of bubble distributions on the propagation of linear waves in polydisperse bubbly liquids
The Journal of the Acoustical Society of America, 2019The influence of the spatial distributions of bubbles on the propagation of linear acoustic waves in polydisperse bubbly liquids is studied. Using the diagrammatic approach, the effective wavenumber, which includes both spatial information and higher orders of multiple scattering, is presented.

Abstract The probability relationships between bubble sizes and chord lengths in an heterogeneously bubbling system have been analyzed. A forward transform of chord length distribution for a given bubble size density distribution affecting the probe under a heterogeneously bubbling condition has been demonstrated. Three backward transform techniques,

Bubble size distribution in a bubble column applied to aquaculture systems
Aquacultural Engineering, 1992Abstract Bubble size distribution affects the gas-liquid mass transfer rates during aeration and foam fractionation processes employed in recirculating aquacultural systems. The effects of air flow rate, protein concentration and air stone pore size on bubble characterization were investigated. Bubble size was measured photographically in conjunction

Bubble size distributions and shapes in annular gap bubble column
Experimental Thermal and Fluid Science, 2016Abstract An understanding of the bubble properties, size distributions and shapes is of fundamental importance for comprehending flow dynamics and mass transfer phenomena in bubble column reactors. A large number of studies have focused on open tube bubble columns, and the knowledge concerning bubble columns with internals is still limited.

Size Distribution of Cavitation Bubbles
2015Acoustic cavitation is defined as the formation of a vapor cavity and bubbles in response to an acoustic field. One can generalize this definition to encompass any observable activity involving a bubble or a population of bubbles stimulated into motion by an acoustic field (Apfel in Methods in Experimental Physics 19:355–411, 1984). There are two basic

Lognormal bubble size distributions
The Journal of the Acoustical Society of America, 2017In the study of oceanic bubbles based on empirical acoustics, the distributions among the sizes are typically represented by power laws with negative slopes as convenient descriptors of data in log/log format. However, power laws do not address the fact that as bubble sizes approach zero their numbers must approach zero.

Gas Bubbles In Distribution Transformers
IEEE Transactions on Power Apparatus and Systems, 1977Gas bubbles are known to have a deleterious effect on the dielectric strength of transformer oil. The possibility that such bubbles may develop in oil-filled distribution transformers and may cause excessive failure rates is thus of concern to both manufacturer and user. The paper presents new information relative to failure mechanisms in transformers.

On the spatial distribution of ocean bubbles
Journal of Geophysical Research: Oceans, 1987Clouds of bubbles generated by breaking waves were detected with a vertically directed high‐frequency echo sounder mounted on a submarine. Bubble concentration was inferred from a simple model of the bubble size distribution. The vertical and horizontal distribution of clouds is discussed in terms of wave‐breaking processes, air‐sea temperature ...
