A new direct technique for visualizing and measuring gas–liquid mass transfer around bubbles moving in a straight millimetric square channel [PDF]
The present paper focuses on the local characterization of gas–liquid mass transfer in a straight millimetric square channel, as constituting the preliminary step required for performing gas–liquid reactions in such devices.

Effect of hydrodynamics on mass transfer in a gas-liquid oscillatory baffled column [PDF]
In this paper, we present an experimental study on mass transfer of oxygen into water in an oscillatory baffled column (OBC). The objective of this work is to establish the contribution of individual parameters, such as the size of bubbles and the gas ...

Hydrodynamic and mass transfer in inertial gas–liquid flow regimes through straight and meandering millimetric square channels [PDF]
Heat-exchanger reactors are an important part of process intensification technology. For plate geometries, one solution for intensifying transfer and increasing residence times is to construct two-dimensional meandering channels.

Direct numerical simulations of mass transfer in square microchannels for liquid-liquid slug flow [PDF]
Microreactors for the development of liquid-liquid processes are promising technologies since they are supposed to offer an enhancement of mass transfer compared to conventional devices due to the increase of the surface/volume ratio.

Hydrodynamics and mass transfer in bubble column: Influence of liquid phase surface tension [PDF]
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 ...
