A Particle-Scale Model of Surface Tension for Two-Phase Flow: Model Description and Validation
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.

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

Gravitational waves from bubble dynamics: beyond the envelope [PDF]
We study gravitational-wave production from bubble dynamics (bubble collisions and sound waves) during a cosmic first-order phase transition with an analytic approach.

Bubble dissolution in horizontal turbulent bubbly flow in domestic central heating system [PDF]
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 ...

Gas–Liquid Mass Transfer around a Rising Bubble: Combined Effect of Rheology and Surfactant
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 ...

Single-bubble and multi-bubble cavitation in water triggered by laser-driven focusing shock waves
In this study a single laser pulse spatially shaped into a ring is focused into a thin water layer, creating an annular cavitation bubble and cylindrical shock waves: an outer shock that diverges away from the excitation laser ring and an inner shock ...

Analysis of the characteristic lengths in the bubble and slug flow regimes generated in a capillary T-junction [PDF]
We present an analysis of the geometry of the continuous and disperse phases in the bubble and slug flow regimes in air–water mixtures generated in a capillary T-junction of 1 mm internal diameter.

We use the notion of a housing bubble as an equilibrium in which some investors hold houses for resale purposes only and not with the expectation of receiving a dividend, either in the form of rent or utility. We show that an economy with looser collateral constraints is less prone to bubbles, which, in turn, have smaller size, but are more fragile in

Study on Bubble Absorption Characteristics of R134a-DMF in Vertical Tube
To study the heat and mass transfer characteristics of an R134a-DMF (Dimethylformamide) bubble absorption process in a vertical tube, an experimental device for bubble absorption in a vertical tube was fabricated, and a mathematical model of heat and ...
