Tribonucleation of bubbles [PDF]
Proceedings of the National Academy of Sciences, 2014 SignificanceMicroscopic gas–vapor bubbles play an important role in various processes in nature, industry, and medicine. Sometimes they are desired: to lower the temperature at which a liquid starts to boil or to enhance the contrast in medical ultrasound applications. In other cases, bubbles are harmful: they cause damage when expanding and collapsing

Mechanical Engineering Journal, 2021 Fission product removal by pool scrubbing is known to be largely affected by the gas-liquid two-phase flow regime. The pool scrubbing performance of various carrier gases was evaluated in two-phase flow experiments by injecting helium, nitrogen, or argon

Investigation of Bubble Characteristics by Photographic Method [PDF]
Iranian Journal of Chemical Engineering, 2022 Most industrial operating units are basically in contact with two gas and liquid phases. Bubble characteristics over the last years have been determined through different methods. In this project a mass transfer system has been designed for absorbing gas

Improving the Performance of Surface Flow Generated by Bubble Plumes
Fluids, 2021 Gas–liquid two-phase flow is widely used in many engineering fields, and bubble dynamics is of vital importance in optimizing the engineering design and operating parameters of various adsorptive bubble systems.

Bubble CPAP: Not All Bubbling Is Good Bubbling [PDF]
Respiratory Care, 2013 Since its introduction over 30 years ago,[1][1] bubble CPAP has become an important part of the management of neonatal respiratory distress syndrome. Similar to “ventilator-derived” or “machine-derived” CPAP devices, bubble CPAP devices apply pressure to the neonatal respiratory system ...

On the representation of the island in my artwork [PDF]
Island Studies Journal, 2015 This essay explores the development of an art project with the island as its central theme. The process is explained through a selection of background material and other considerations that have led to the eventual work.

Mathematical model for bulk modulus of hydraulic oil containing air bubbles
Mechanical Engineering Journal, 2015 Hydraulic systems have high-power density because its oil transmitting power has high rigidity. However, when air bubbles are mixed into oil, they reduce oil stiffness and decrease system efficiency.

Graphical Models, 2009 We present a novel framework based on a continuous fluid simulator for general simulation of realistic bubbles, with which we can handle as many significant dynamic bubble effects as possible. To capture nature of the very thin liquid film of bubbles, we have developed a regional level set method allowing multi-manifold interface tracking. The regional
