Liquid-liquid two-phase flow patterns and mass transfer characteristics in rectangular glass microreactors
TL;DR: In this article, the shape of the interface between the immiscible liquids was controlled by a competition between the viscous forces and the local interfacial tension, and the mass transfer coefficients for parallel and slug flow were determined using instantaneous eutralisation (acidbase) reaction.

The intensification of rapid reactions in multiphase systems using slug flow in capillaries
John Burns,Colin Ramshaw +1 more
TL;DR: A multiphase microreactor based upon the use of slug flow through a narrow channel has been developed and the internal circulation, which is stimulated within the slugs by their passage along the channel, is responsible for a large enhancement in the interfacial mass transfer and the reaction rate.

Internal Circulation within the Liquid Slugs of a Liquid-Liquid Slug-Flow Capillary Microreactor
TL;DR: In this article, the internal circulation of a slug was modeled as a distinct single-phase flow domain and the effect of the flow velocity and slug length on the velocity profile and stagnant zones of the internal circulations with and without a wall film was discussed.
