When pipelines are transporting bubbly fluid medium, due to the coalescence and breakage behaviours of the bubbles, the pressure distribution at the wall is not uniform and the structure response is more complex.

Reaction Systems for Bubbly Flows [PDF]
Reactive bubbly flows are at the heart of multiphase flows which are a major topic in chemical engineering since many bulk chemicals are produced in bubbly flows. However, the factors determining product yield and selectivity are often subject of complicated mass transfer effects.

Vortex Simulation of the Bubbly Flow around a Hydrofoil
This study is concerned with the two-dimensional simulation for an air-water bubbly flow around a hydrofoil. The vortex method, proposed by the authors for gas-liquid two-phase free turbulent flow in a prior paper, is applied for the simulation.

Strong interactions bubble/bubble and bubble/flow [PDF]
The study of bubble dynamics in non-uniform flow fields is fundamental to the ability to predict or explain any cavitation effects in real flow fields. In this presentation we describe our recent contributions towards the fundamental understanding of bubble dynamics in non-uniform flow fields when large bubble deformations and bubble interactions are ...

Transition Criterion of Bubbly-slug Flow Pattern in Rectangular Narrow Channel
In the two-phase flow system, the flow pattern affects the frictional resistance and heat transfer characteristics of the system. Accurate identification of different flow patterns is of great significance to the calculation of twophase flow.

Bubbles and bubbly flows are omnipresent in nature and technology, showing a multitude of phenomena, which can be either beneficial or a hindrance. In any case, for their control and their applications, it is crucial to understand their fundamentals and therefore from the very beginning of the International Journal of Multiphase Flow they have been ...

Statistical equilibrium of bubble oscillations in dilute bubbly flows [PDF]
The problem of predicting the moments of the distribution of bubble radius in bubbly flows is considered. The particular case where bubble oscillations occur due to a rapid (impulsive or step change) change in pressure is analyzed, and it is mathematically shown that in this case, inviscid bubble oscillations reach a stationary statistical equilibrium,
