Heat transfer coefficients measured in a 0.15 m ID bubble column are compared with similar
studies in larger diameter columns to identify influence of column diameter. Gas phase used …

Bubble mass transfer is a common phenomenon in industrial applications. In this paper,
bubble dynamics in both still and turbulent flow were introduced first, followed by the mass …

Effective gas-liquid mixing is critical for the successful implementation of ozonation and
advanced ozone-based oxidation technologies. This study focuses on a static-mixer-based …

Bubble columns reactor is widely used as gas–liquid mixing and as reactors in many
industries especially in chemical, petrochemical and biochemical processing. High …

Image analysis technique has been proved to be very effective in the quantification of
particles size and morphology distributions in different work areas. In the present work this …

An experimental study has been carried out to investigate the effect of internals and sparger
design on mixing time (θmix) and fractional gas hold-up (ɛG) in a batch mode sectionalized …

Publisher Summary This chapter provides an overview of the experiment conducted on the
local bubble size distribution in stirred vessels using phase doppler anemometry. The local …

New correlations have been proposed for estimation of gas phase holdup, characteristic
velocity, interfacial area for mass transfer and mean bubble size of bubble swarms under …

In this numerical study, the bubble injection effect on the heat transfer rate is investigated
next to an inclined heated wall. The volume of fluid (VoF) method solver in the OpenFOAM …

Mixing is an important unit operation in the process industry. Ensuring homogeneity of slurry
or emulsion is critical for subsequent processing or to improve the efficacy of reactions, and …
