Numerical and experimental investigation of a confined plunging liquid jet system [PDF]
, 2012 In a confined plunging liquid jet (CPLJ) system, a liquid jet is allowed to fall in a partially submerged narrow downcomer tube. Liquid jet impingement at gas-liquid interface leads to entrainment of gas, which is dispersed down the downcomer tube in to ...

Hydrodynamics and mass transfer in bubble column: Influence of liquid phase surface tension [PDF]
, 2007 According to literature, few experiments are performed in organic solvents which are mostly used in commercial gas–liquid reactors. However, it is commonly accepted that data obtained in aqueous solution allow to predict the surface tension effects, and ...

On the reliability of an optical fibre probe in bubble column under industrial relevant operating conditions [PDF]
, 2007 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.
