Mass transfer between bubbles and seawater

Mass Transfer from Growing and Oscillating Rising Bubbles

Mass transfer in gas liquid systems depends on the contact between the entities in which the gas phase is dispersed into the liquid, the bubbles, and the surrounding liquid. Further knowledge of the hydrodynamics of the growing and rising bubbles under mass transfer conditions will help in the understanding of the mass transfer process in bubble columns and in the design of the equipment.

Visualization of gas–liquid mass transfer and wake structure of rising bubbles using pH-sensitive PLIF

A planar laser-induced fluorescence (PLIF) technique for visualizing gas–liquid mass transfer and wake structure of rising gas bubbles is described. The method uses an aqueous solution of the pH-sensitive dye Naphthofluorescein and CO2 as a tracer gas. It features a high spatial resolution and frame rates of up to 500 Hz, providing the ability to capture cinematographic image sequences. By stee...

Effect of Seawater on Micro-Nano Air Bubbles Concrete for Repair of Coastal Structures

This paper investigated the effects of seawater curing of concrete made by Micro-Nano Air Bubbles (MNAB) on compressive, flexural and tensile strengths of the concrete. This product will be applicable for rehabilitation or repair of coastal RC structures. In this research, the effect of different combinations of concrete ingredients including 0-100, 25-75, 50-50, 75-25, and 100-0 percent ...

Mass Transfer between Double White Dwarfs

Three periodically variable stars have recently been discovered (V407 Vul, P = 9.5 min; ES Cet, P = 10.3 min; RX J0806.3+1527, P = 5.3 min) with properties that suggest that their photometric periods are also their orbital periods, making them the most compact binary stars known. If true, this might indicate that close, detached, double white dwarfs are able to survive the onset of mass transfe...
