Two-Phase Bubble Columns: A Comprehensive Review
We present a comprehensive literature review on the two-phase bubble column; in this review we deeply analyze the flow regimes, the flow regime transitions, the local and global fluid dynamics parameters, and the mass transfer phenomena.

3D Simulation and Validation of a Lab Scale Bubble Column
Bubble columns are widely used in the chemical, petrochemical and biochemical industry. The correct prediction of the fluid dynamics, gas hold-up and bubble size distribution is of importance for the design and development of such reactors.

On the reliability of an optical fibre probe in bubble column under industrial relevant operating conditions [PDF]
When bubble columns are operated under industrial relevant conditions (high gas and liquid flow rates, large bubbles and vortices,. . .), local data, and especially bubble size values, are difficult to obtain.

Liquid-Phase Back mixing in Bubble Columns
Liquid-phase axial dispersion coefficients have been measured for air-water system in bubble columns of 10, 15 and 30 cm diameter. The experiments are carried out using a transient method (the tracer response method).

Numerical Simulation of Hold-up and Velocity Profiles for Two-phase Developed Flows in a Column
The purpose of this article is to simulate and analyse two-phase fluid dynamics in a bubble column, through two different numerical approaches, in a fast and effective way, to minimize project costs and increase productivity.

EXPERIMENTAL STUDY OF LIQUID DISPERSION IN BUBBLE COLUMN
The main object of this study is to investigate the influence of column diameter and superficial gas velocity on liquid phase dispersion coefficients (axial and radial dispersion coefficients), mixing times, gas holdup, and bubble dynamics (bubble ...

Numerical Simulation of Poly-Dispersed Bubbly Flow Using a Multi-Fluid Model
Numerical methods for predicting poly-dispersed bubbly flows in bubble columns are indispensable in the design of bubble column reactors. The objectives of the present study are (1) to experimentally investigate the effects of a bubble size distribution ...

Fluid dynamics of gas-liquid bubble columns [PDF]
Gas-liquid bubble columns are used extensively in the process industries. The gas-liquid twophase flow prevailing in this type of process equipment is extremely complex, inherently unsteady and dominated by phenomena with widely varying time- and length ...
