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

Electroweak bubble wall speed limit [PDF]
, 2017 In extensions of the Standard Model with extra scalars, the electroweak phase transition can be very strong, and the bubble walls can be highly relativistic.

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

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

Bubble puzzles: From fundamentals to applications [PDF]
Physical Review Fluids, 2018 For centuries, bubbles have fascinated artists, engineers, and scientists alike. In spite of century-long research on them, new and often surprising bubble phenomena, features, and applications keep popping up.
