Bubble formation at a flexible orifice with liquid cross-flow [PDF]
, 2004 In waste water treatment, biological processes for denitrification and nitrification are performed using oxidation ditches. In these reactors, the mixing and the aeration functions are dissociated: a bubble cloud is generated from flexible membrane ...

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 ...

Hydrodynamics, acoustics and scaling of traveling bubble cavitation [PDF]
, 1994 Recent observations of the geometries of growing and collapsing bubbles over axisymmetric headforms have revealed the complexity of the "microfluidmechanics" associated with these flows (Hamilton et al., 1982, Briancon Marjollet and Franc, 1990, Ceccio ...

IEEE Access, 2019 Metal particles and bubbles are two typical impurities in transformer oil that can cause partial discharge (PD) and even electric breakdown. The PD characteristics are closely related to the motions of these impurities in flowing transformer oil. In this

Bubble formation from a flexible hole submerged in an inviscid liquid [PDF]
, 2003 In the waste water treatment industry, a novel gas sparger based on flexible membranes has been used for the last ten years. The objective of the present work is to study the bubble formation generated from a flexible orifice (membrane).

Macroeconomic Dynamics, 2007 In an attempt to clean up an unruly literature, we specify the necessary and sufficient conditions for household optimality in a model where money is the only financial asset and provide the relevant proofs. We use our results to analyze when deflationary bubbles can and cannot exist.

Experimental Study of Flow Boiling Regimes Occurring in a Microfluidic T-Junction
Micromachines, 2023 Microchannel flow boiling is an efficient cooling method for high-heat-flux electronic devices. To understand the flow boiling regime in a T-shaped microchannel, this paper prepared T-shaped microchannels of different sizes and designed an experimental ...
