Bubbly flows involve bubbles randomly distributed within a liquid. At large Reynolds
number, they experience an agitation that can combine shear-induced turbulence (SIT) …

Photobioreactor (PBR) is the most critical equipment for microalgal photosynthetic fixation of
CO 2. It provides suitable environmental conditions, such as CO 2, light and nutrients, for …

This article presents a state-of-the-art review focusing on the current understanding of the
multiscale multiphase phenomena inside Bubble Column Reactors (BCRs). Although many …

This paper presents a robust image processing technique for bubbly flow measurement over
a wide range of void fractions. The proposed algorithm combines geometrical, optical and …

Bubbly flow is a prototypical two-phase flow problem. The dynamic behavior of bubbles
within a reactor is intrinsically linked to their transport, distribution, and mass transfer, all of …

We report on an investigation of bubble-induced turbulence. Bubbles of a size larger than
the dissipative scale cannot be treated as pointwise inclusions, and generate important …

We perform direct numerical simulations of a gas bubble dissolving in a surrounding liquid.
The bubble volume is reduced due to dissolution of the gas, with the numerical …

This work reports an experimental characterisation of the flow properties in a homogeneous
bubble swarm rising at high Reynolds numbers within a homogeneous and isotropic …

It is important to understand the gas–liquid mass-transfer performance for the reactor design
and scale-up of bubble columns. Air-water bubble columns have been extensively …

This study aims at improving the knowledge on the effects of gas injection, bubbles sizes
and contaminants on oxygen transfer in microbubble clouds. First the effects of gas injection …
