Numerical simulation of bubble generation in a T-junction [PDF]
, 2012 We present a numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM. Numerical simulations were carried out for different flow conditions, giving rise to results on the behavior of bubble ...

Numerical Investigation of Helium Bubble Rising Behavior in Cross-Type Channel
Frontiers in Energy Research, 2020 In a certain nuclear reactor, the coolant channel is a cross-type channel. There is little research about bubble rising behavior in this kind of channel, but the neutron detection would be affected by the bubbles.

Bubbles Tomorrow and Bubbles Yesterday, but Never Bubbles Today? [PDF]
Business Economics, 2013 Considering their importance and the amount of effort that has gone into understanding them, asset price bubbles continue to perplex. The evidence of these bubbles seldom squares with what would be expected from standard asset price theory. Unlike the suggestions from theory, expectations of prices of both stocks and houses tend to be procyclical—price

Bubble growth in a two-dimensional viscoelastic foam [PDF]
, 2006 The effects of viscoelasticity on the expansion of gas bubbles arranged in a hexagonal array in a polymeric fluid are investigated. The expansion is driven by the diffusion of a soluble gas from the liquid phase, and the rate of expansion is controlled ...

Surface heat transfer due to sliding bubble motion
, 2009 The presence of a rising bubble in a fluid can greatly enhance heat transfer from adjacent heated surfaces such as in shell and tube heat exchangers and chemical reactors.

Shear-free boundary in Stokes flow
International Journal of Mathematics and Mathematical Sciences, 1996 A theorem of Harper for axially symmetric flow past a sphere which is a stream surface, and is also shear-free, is extended to flow past a doubly-body 𝔅 consisting of two unequal, orthogonally intersecting spheres. Several illustrative examples are given.

Effectiveness of rituximab in the treatment of patients with pemphigus vulgarus [PDF]
Vestnik Dermatologii i VenerologiiPemphigus vulgaris (PV) is an autoimmune disease that affects the mucous membranes and/or skin, characterized by the formation of bubbles of various sizes with a thin flaccid cap and serous contents. Lack of timely treatment can lead to death. Due to the

Blowing bubbles: Dermoscopy of bubble hair
International Journal of Trichology, 2017 Exposing wet hair to high temperatures can create gas bubbles within the hair shaft, leading to brittle, dry hairs in a disorder known as bubble hair abnormality. We present a case of a 61-year-old woman who presented for hair breakage over her crown. She regularly dried her damp hair with a blow dryer.

Numerical simulation of bubble dispersion in turbulent Taylor-Couette flow [PDF]
, 2014 We investigate bubble dispersion in turbulent Taylor-Couette flow. The aim of this study is to describe the main mechanisms yielding preferential bubble accumulation in near-wall structures of the flow.
