Using a Lagrangian-Lagrangian approach for studying flow behavior inside a bubble column
Bubble columns are widely encountered in several industries, especially in the field of nuclear safety. The Eulerian-Eulerian and the Eulerian-Lagrangian methods are commonly used to investigate bubble columns.

Fluid Dynamic in Bubble Columns with Heat Exchanger Internals [PDF]
The effects of vertical cooling internals on the gas hydrodynamics was studied in gas-liquid system (bubble columns) for column diameters, 15 and 30 cm in the absence and presence of internals (the % occluded area by internals 5, 10, and 20%).

Breaking the Rayleigh-Plateau instability limit using thermocavitation within a droplet [PDF]
We report on the generation of liquid columns that extend far beyond the traditional Rayleigh-Plateau instability onset. The columns are driven by the acoustic pressure wave emitted after bubble collapse.

Investigation of Operating Parameters’ Effects on Bubble Characteristics in a Co-Current Downflow Bubble Column [PDF]
Bubble columns are frequently employed as multiphase reactors and gas-liquid contactors. In the bubble column, gas is dispersed into the liquid phase. The dispersion of gas into a liquid is the function of bubble size and its distribution.
