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 …

Processes and manufacturing in the biopharmaceutical industry are mainly based on
experimental data and statistical approaches, however, regulatory expectations of …

The efficiency of ejector-based systems (the “system-scale”) relies on the behaviour of the
ejector (the “component-scale”), related to the flow phenomena within the component itself …

The applications of ejectors are many and encompass the refrigeration, the power
generation and the chemical sectors. On one hand, ejector technology needs limited …

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 …

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 …

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 …

Boiling flows are frequently found in industry and engineering due to the large amount of
heat that can be transferred within such flows with minimum temperature differences. In 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' …
