Bubble-size distributions in foams
Advances in Colloid and Interface Science, 1992Abstract Bubble-size distributions in foams can be used to study foam properties and to distinguish between the physical processes that contribute to the breakdown of the foam. These processes are drainage, coalescence and disproportionation. A new Foam Analyzer was developed to measure various foam characteristics like the rate of drainage, the rate

Bubble size estimation in a bubble swarm
Journal of Colloid and Interface Science, 1988Abstract The hindered settling equations of J. H. Masliyah (Chem. Eng. Sci.34, 1166 (1979)) have been adapted to predict mean bubble size in bubble swarms. The measurements required are superficial liquid and gas rates, and gas holdup. Predicted and measured (by photography) bubble sizes agree within 15% over the tested range 0.5–1.5 mm.

Bubble size distribution in bubble columns
The Canadian Journal of Chemical Engineering, 1990AbstractThe bubble size distributions are measured for the air‐water system as a function of air velocity at room temperature in two bubble columns. High speed cinephotography and fiber optic probe techniques are used to measure the bubble size. Our limited measurements suggest that the bubble size may be independent of gas velocity in the range 3.6 to

Bubble sizing with a high spatial resolution
IEEE 1988 Ultrasonics Symposium Proceedings., 1990The authors propose a technique that allows them to size bubbles with the same accuracy as with the double-frequency method and to locate them with the same range resolution as with the pulsed Doppler velocimeter. They demonstrate that the signal scattered by the bubble insonified by a high-frequency pulsed ultrasonic field and a low-frequency pumping ...

Prediction of the bubble-hole size of a cap bubble in a bubble swarm
Chemical Engineering Science, 1997Abstract A phenomenological, semi-theoretical model is proposed for predicting the size or thickness of the bubble-depleted region, or ‘bubble hole’, in the frontal vicinity of a larg cap bubble rising through a swarm of otherwise uniformly dispersed small bubbles.

Factor Affecting Bubble Creation and Bubble Size
Volume 1: Advances in Aerospace Technology; Energy Water Nexus; Globalization of Engineering; Posters, 2011This paper presents the factors affecting air bubble size when air is injected through a perforated membrane into a water pool. Critical factors that govern the size of air bubbles are the air pressure and the flow rate as well as the hole size of the diffuser membrane. In order to have a better understanding of how bubble size can be affected and what

Optical monitoring of bubble size and shape in a pulsating bubble surfactometer
Journal of Applied Physiology, 2005The pulsating bubble surfactometer (PBS) is often used for in vitro characterization of exogenous lung surfactant replacements and lung surfactant components. However, the commercially available PBS is not able to dynamically track bubble size and shape.
