Gas Holdup and Liquid-Phase Dispersion in Packed Bubble Columns

Tikrit Journal of Engineering Sciences, 2011
The gas holdup and liquid phase axial dispersion coefficient are measured in two semi batch packed bubble columns, 10 and 15 cm diameter for an air–water system, at atmospheric conditions.

Variable-column bubble oxygenator A new system for bubble oxygenation

The Journal of Thoracic and Cardiovascular Surgery, 1975
A new bubble oxygenator has been developed. Its main advantage is that the dimensions of the oxygenating chamber can be varied. Thus, the capacity for oxygenation may be adapted to different patients. It was used in 2,700 open-heart operations performed at the Institut do Coracão, Faculdade de Medicina, Universidade de São Paulo, between January, 1971,

Polydispersity Effects in the Dynamics and Stability of Bubbling Flows

, 2005
The occurrence of swarms of small bubbles in a variety of industrial systems enhances their performance. However, the effects that size polydispersity may produce on the stability of kinematic waves, the gain factor, mean bubble velocity, kinematic and ...

Plasma Turbulence in the Local Bubble

, 2008
Turbulence in the Local Bubble could play an important role in the thermodynamics of the gas that is there. The best astronomical technique for measuring turbulence in astrophysical plasmas is radio scintillation.

Impact of Solid Particle Concentration and Liquid Circulation on Gas Holdup in Counter-Current Slurry Bubble Columns

Fluids
In this study, in a three-phase reactor with a rectangular cross-section, the effects of liquid circulation rates and solid particle concentration on gas holdup and bubble size distribution (BSD) were investigated.

Molecular Lines of 13 Galactic Infrared Bubble Regions

, 2016
We investigated the physical properties of molecular clouds and star formation processes around infrared bubbles which are essentially expanding HII regions. We performed observations of 13 galactic infrared bubble fields containing 18 bubbles.
