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 …

In this study, a modified gas feeding bubble column photo-bioreactor was utilized for
microalgae cultivation and CO 2 capturing. By applying response surface methodology, the …

Bubble columns are used in many industrial applications, but the complex fluid dynamics
phenomena has limited their design and optimization processes. Computational Fluid …

Unsteady and three-dimensional Eulerian–Eulerian CFD simulations of bubble column
reactors under operating conditions of industrial interest are discussed in this work. The flow …

Oxygen transfer is a key element in aerobic fermentations, especially if the culture broth's
rheology is non-Newtonian, as in the case of cultures of filamentous fungi. Viscosity …

Industrial bubble columns generally operate under the so-called heterogeneous regime and
with high gas volume fractions, implying a fundamental role of the coalescence and …

The mass transfer of gas–liquid systems is commonly reported through the volumetric mass
transfer coefficient, k L a, which is a function of several complex phenomena. To optimize the …

Customers post online reviews at any time. With the timestamp of online reviews, they can
be regarded as a flow of information. With this characteristic, designers can capture the …

Due to their widespread application there is substantial academic and industrial interest in
modelling the hydrodynamics of bubble columns. To this end there is a need to develop and …
