An assessment is given of the present state of modeling and simulation of buoyancy driven
gas‐liquid bubble flow based on the two‐fluid approach. Main points of discussion comprise …

Current worldwide commercial activities in converting natural gas to fuels and chemicals, or
gas-to-liquids technology use slurry bubble column reactors with column sizes considerable …

Despite the fact that bubble columns are widely established within the process industry as
multiphase reactors and gas–liquid contactors, common research has been focused on the …

Lateral migration of a single bubble rising in the vicinity of a vertical flat plate was measured
to evaluate a wall force acting on the bubble. Experimental results indicated that a wall force …

Hydrodynamic characteristics of bubble columns are studied by considering both the
local/bubble‐scale and global/column‐scale properties of the system, with specific …

In relation to the development of the interfacial area transport equation, the basic concept of
two-group interfacial area transport equations was demonstrated. This study focused on (1) …

This paper presents an extensive review of the kinetics, hydrodynamics, mass transfer, heat
transfer and mathematical as well as computational fluid dynamics (CFD) modeling of Low …

Some aspects of bubble dynamics and macroscopic hydrodynamic properties in high-
pressure bubble columns and three-phase fluidization systems are discussed. Experimental …

The effective viscosity which characterizes the pseudo-homogeneous property of the liquid-
solid suspension in gas-liquid-solid fluidization is examined in light of the velocity of single …

Radial distributions of void fraction αG, bubble aspect ratio E, phasic velocities VG and VL
and turbulent kinetic energy k in bubbly pipe flows are measured using an image processing …
