We present a comprehensive literature review on the two-phase bubble column; in this
review we deeply analyze the flow regimes, the flow regime transitions, the local and global …

Mixing is a ubiquitous operation in process engineering. It is not only used for combining
materials, but also for promoting heat and mass transfer, increasing aeration, suspending …

Some authors, in the last decades, have observed the dual effect of viscosity on gas holdup
and flow regime transition in small-diameter and small-scale bubble columns. This work …

The influence of viscosity and surface tension on bubble dynamics and gas liquid mass
transfer has been examined experimentally in a model bubble column using optical …

The correct design, operation and scale-up of bubble columns rely on the knowledge of the
fluid dynamics at the “bubble-scale” and at the “reactor-scale”. This paper contributes to the …

Bubble columns are gas–liquid contactors that are used in many process-engineering
applications. A counter-current liquid flow is frequently imposed to adjust the bubbles' …

An understanding of the fluid dynamics and the transport phenomena in bubble columns (in
the homogeneous and heterogeneous flow regimes) is of fundamental importance to …

The aim of this study is to identify the flow structure in an airlift pump–bubble generator
system by using experimentally obtained differential pressure signals. Differential pressure …

In the study of meso-scale structures of multi-phase flow in bubble columns, accurate
modelling of the interaction between the turbulence eddies and particle/bubble groups is …

Gas-liquid two-phase bubbly flow widely exists in the field of natural gas extraction. The
identification and feature extraction of bubbles are becoming more and more important to …
