The ongoing expansion of industries results in the increased emission of various pollutants
into the environment, contributing to the rapid deterioration of air, water, and soil quality …

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 …

The performance of four bioreactors (bubble column, concentric tube airlift, concentric tube
stirred airlift, and mechanically stirred tank) were evaluated in this study in terms of the …

An in-depth examination of the hydrodynamics of gas-solid fluidized beds at high
temperature and pressure is critical for their design and operation owing to the global trend …

The growing global population and heightened concern for climate change leads to
increased interest in utilizing microbial fermentations to replace polluting production …

Bubble dynamic behaviors have significant effects on the interfacial area between gas and
liquid phases, the gas-phase residence time and the efficiency of heat and mass transfer …

The simultaneous effect of particle size and concentration on the total gas holdup of slurry
bubble column reactors was investigated in this work. The total gas holdup was measured …

Splitting of the volumetric mass transfer coefficient into a bubble–liquid mass transfer
coefficient and interfacial area is essential to quantify the mass transfer rate of stirred tanks …

Mass transfer is a crucial phenomenon in designing and scaling up chemical and
biochemical stirred tanks. The literature lacks a pilot-scale study on investigating mass …

Complexities in the hydrodynamics of slurry bubble columns lead to noticeable uncertainty
in the design and scale-up of these multiphase reactors. Knowledge of local hydrodynamics …
