Measurements of bubble diameter in bubble swarm in water by the sound pulse response method.

The impact of wind-generated bubble layer on matched field sound source localization in shallow water (Research Article)

This paper investigates the effect of the wind-generated bubble layer on the underwater sound source localization in the Persian Gulf shallow-water environment through computer simulation and the matched field processing technique. An underwater sound source of 2-10 kHz located at depths of 10, 45, and 75 m was considered at a distance of 4 km from a linear vertical receiver array. The estimati...

ADV measurements in a flotation tank with bubble containing water

Dissolved Air Flotation (DAF) is a method for separating suspended, microscopic particles in water and wastewater treatment. The basic idea is to generate huge amounts of microscopic bubbles, which should attach to the particles whereby less dense aggregates are obtained, rising to the water surface. The flow structure in a flotation tank is important for the separation efficiency. ADV measurem...

Air Bubble Growth in Water

To the Editor:—I read with considerable interest the article by Benavides et al. describing experiments of air bubble growth in water during exposure to 100% nitrous oxide, 100% xenon, or 50% xenon–50% oxygen. Although the experiments were nicely conducted, they explore a physics of gas flux in an unconstrained bubble permitted to grow spherically. Importantly, this geometry has limited biologi...
