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 ...

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.

JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 2008 In this study, a theoretical model for prediction of bubbling regimes in bubble formation from a single submerged orifice has been developed. The model takes into account both chamber pressure fluctuations, and bubble–bubble and bubble–wall interactions on bubbling regimes.

Numerical Simulation of Poly-Dispersed Bubbly Flow Using a Multi-Fluid Model
Journal of Fluid Science and Technology, 2007 Numerical methods for predicting poly-dispersed bubbly flows in bubble columns are indispensable in the design of bubble column reactors. The objectives of the present study are (1) to experimentally investigate the effects of a bubble size distribution ...

Semi-Analytical Model for Heat and Mass Transfer Evaluation of Vapor Bubbling
Energies, 2020 Multi-stage refrigeration systems cover a wide range of possibilities and are diffusing more and more. The idea that inspired this work derived from the need to have a tool to model the energy behavior of the intercooler inside a multi-stage ...

Fate of bubble clusters rising in a quiescent liquid [PDF]
arXiv, 2023 We use experiments to study the evolution of bubble clusters in a swarm of freely rising, deformable bubbles. A new machine learning-aided algorithm allows us to identify and track bubbles in clusters and measure the cluster lifetimes. The results indicate that contamination in the carrier liquid can enhance the formation of bubble clusters and prolong
