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 …

This article offers an overview of the instrumentation techniques developed for multiphase
flow analysis either in gas/liquid or in gas/liquid/solid reactors. To characterise properly such …

Measurements of bubble and pellet size distributions are useful for biochemical process
optimizations. The accuracy, representation, and simplicity of these measurements improve …

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 …

An understanding of the bubble properties, size distributions and shapes is of fundamental
importance for comprehending flow dynamics and mass transfer phenomena in bubble …

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 …

In this paper, we apply a variety of experimental techniques to investigate the influence of
the counter-current mode on bubble column hydrodynamics. We study an air–water bubble …

A precise estimation of bubble size distributions and shapes is required to characterize the
bubble column fluid dynamics at the “bubble-scale”, and to evaluate the heat and mass …

This work is a study of the effect of liquid properties and pore size on the initial bubble size
distribution of a bubble column equipped with fine pore sparger. Various liquids covering a …

Although gas–liquid bubbly flows are encountered in various engineering fields, there are
very few established theoretical foundations on the interfacial area concentration, which …
