Bubble columns are cylindrical vessels wherein gas is sparged, via a distributor, in the form
of bubbles, into liquid or liquidsolid suspension. Bubble columns serve as multiphase …

Numerous experimental results concerning the flow structure in bubble columns are
presented, including axial and radial components of the bubble velocity, axial components …

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

The state of the art of the modelling of gas—liquid flow in bubble columns and loop reactors
is critically reviewed. Recent results obtained with dynamic multidimensional two-fluid …

This paper focuses on the modeling of flow and mixing in a bubble column reactor operated
at high gas velocities (up to 0.40 m/s). A dual-tip conductivity probe was used to measure …

Gas–liquid flow in bubble columns is inherently unsteady. The unsteady fluid dynamics
influences mixing and other transport processes occurring in bubble column reactors. In this …

Recently bubble columns have been tested as bioreactors for the manufacture of single-cell
protein and yeast production and used extensively for pilot coal liquefaction reactions. Gas …

Bubble‐size distributions and flow fields in bubble columns are calculated numerically. The
population balance is simplified and reduced to a balance equation for the average bubble …

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 …
