The Month-of-the-Year Effect in the European, American, Australian and Asian Markets
Economies, 2021 This paper examines the existence of the month-of-the-year effects in four different continents, namely Europe, Asia, America, and Oceania. Nine indexes were analyzed in order to verify differences between monthly returns from January 1990 to December ...

First Observational Tests of Eternal Inflation [PDF]
, 2011 The eternal inflation scenario predicts that our observable Universe resides inside a single bubble embedded in a vast inflating multiverse. We present the first observational tests of eternal inflation, performing a search for cosmological signatures of

Graphical Models, 2009 We present a novel framework based on a continuous fluid simulator for general simulation of realistic bubbles, with which we can handle as many significant dynamic bubble effects as possible. To capture nature of the very thin liquid film of bubbles, we have developed a regional level set method allowing multi-manifold interface tracking. The regional

Bubble dissolution in horizontal turbulent bubbly flow in domestic central heating system [PDF]
, 2013 In a domestic central heating system, the phenomenon of microbubble nucleation and detachment on the surface of a boiler heat exchanger finds its origins in the high surface temperature of the wall and consequential localised super saturation ...

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.

A Particle-Scale Model of Surface Tension for Two-Phase Flow: Model Description and Validation
Energies, 2022 A particle-scale surface tension force model (STF) is proposed here to be incorporated in the smoothed hydrodynamics particle (SPH) method. This model is based on the identification of interface geometry and the gradient of densities across the interface.

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.

Gas–Liquid Mass Transfer around a Rising Bubble: Combined Effect of Rheology and Surfactant
Fluids, 2021 The influence of viscosity and surface tension on oxygen transfer was investigated using planar laser-induced fluorescence with inhibition (PLIF-I). The surface tension and the viscosity were modified using Triton X-100 and polyacrylamide, respectively ...
