Mass or heat transfer inside a spherical gas bubble at low to moderate Reynolds number [PDF]

open access: yes, 2013
Mass (or heat) transfer inside a spherical gas bubble rising through a stationary liquid is investigated by direct numerical simulation. Simulations were carried out for bubble Reynolds number ranging from 0.1 to 100 and for Péclet numbers ranging from 1

Comparison of PD and Breakdown Characteristics Induced by Metal Particles and Bubbles in Flowing Transformer Oil

open access: yesIEEE 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

Toward Enhanced Aerosol Particle Adsorption in Never‐Bursting Bubble via Acoustic Levitation and Controlled Liquid Compensation

open access: yesAdvanced Science, 2023
Bubbles in air are ephemeral because of gravity‐induced drainage and liquid evaporation, which severely limits their applications, especially as intriguing bio/chemical reactors.

Analysis of Evaporative Heat Transfer by Expansion Bubble in a Microchannel for High Heat Flux Cooling

open access: yesJournal of Thermal Science and Technology, 2012
The objectives of this study were to establish a theoretical model of the phase change heat transfer in a microchannel and to investigate the possibility of cooling under higher heat flux than the critical heat flux for nucleate boiling.

Experimental Study of Flow Boiling Regimes Occurring in a Microfluidic T-Junction

open access: yesMicromachines, 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 ...

Dynamics of a two-dimensional vapor bubble confined between superheated or subcooled parallel plates [PDF]

open access: yes, 2010
The dynamics of a long, two-dimensional vapor bubble confined in the gap between two superheated or subcooled parallel plates is analyzed theoretically. The unsteady expansion and/or contraction of the bubble is driven by mass transfer between the liquid

Acoustics of Bubble Arrays: Role Played by the Dipole Response of Bubbles

open access: yesFluids, 2018
A model for acoustic transmission through a 2D square crystal of R-radius bubbles with a lattice constant L was previously proposed. Assuming a purely monopole response of the bubbles, this model offers a simple analytical expression of the transmission.

The Effect of Bubbles on Particle Migration in Non-Newtonian Fluids

open access: yesSeparations, 2021
The movement of the gas–liquid interface caused by the movement of the bubble position will have an impact on the starting conditions for particle migration.

Bubble Lift-off Size in Forced Convective Subcooled Boiling Flow [PDF]

open access: yes, 2005
Forced convective subcooled boiling flow experiments were conducted in a BWR-scaled vertical upward annular channel. Water was used as the testing fluid, and the tests were performed at atmospheric pressure.

Demonstration by Infra-Red Imaging of a Temperature Control Defect in a Decompression Sickness Model Testing Minocycline

open access: yesFrontiers in Physiology, 2019
The prevention, prognosis and resolution of decompression sickness (DCS) are not satisfactory. The etiology of DCS has highlighted thrombotic and inflammatory phenomena that could cause severe neurological disorders or even death.
