In this paper, the effects of dense vertical internals (rods) on gas holdup and local gas and
liquid velocities were investigated by using the Eulerian-Eulerian model coupled with the …

The effects of the presence of the vertical internals of different sizes at a wide range of
superficial gas velocity on the overall, local gas holdup distributions and their profiles have …

An advanced gamma-ray computed tomography (CT) technique was used for the first time to
visualize and quantify the impacts of the presence of heat-exchanging tubes and their …

In this work, the hydrodynamics of a bubble column with vertical heat exchanger internals in
a narrow bubble column of D i= 0.1 m inner diameter with a clear liquid height of L c= 1.1 m …

The impact of dense vertical internal tubes and their configurations on the gas holdup
distributions and their diametrical profiles in pilot-scale bubble column is visualized and …

This study identifies and addresses some major pitfalls that are involved in the visualization
and quantification of the gas‐liquid distributions and their profiles in a bubble column with …

A four-point optical fiber probe technique was employed in a split-cylinder airlift reactor with
an air-water system. Effect of superficial gas velocities-0.3, 1.0, 2.0, and 2.8 cm/s-was …

The effects of the presence of vertical internal tubes and their diameters on the local gas
holdup and bubble dynamics, including the specific interfacial area, bubble chord length …

Bubble column reactors with exothermic reactions are often equipped with dense tube
bundle heat exchangers. While there is some knowledge about the impact of such internals …

The complex flow patterns in bubble columns can be phenomenologically described by the
two-bubble class approach. For the first time, this approach is applied to bubble columns …
