Mass transfer in the wake of non-spherical air bubbles quantified by quenching of fluorescence

 M. Jimenez, N. Dietrich, G. Hébrard, Chem. Eng. Sci. (2013)   Full paper here Abstract Based on planar laser induced fluorescence with inhibition (PLIFI) experiments, the mass transfer behavior in the wake of single rising air bubbles is investigated. Bubbles of equivalent diameters ranging from 0.90 to 2.24 mm are studied, exhibiting vertical and zigzagging paths […]

Multi-scale analysis of physicochemical parameters on the hydrodynamic and gas-liquid mass transfer in thriphasic reactor

Property of Abderrahmane Kherbechea, Nicolas Dietrich, Gilles Hébrard and Brahim Lekhlif; 2012 The use of three-phasic reactors in industrial sector remains, today, the priority of lot of researches around the world,  three-phasic reactors, so-called biofilters in wastewater treatment domain, are widely used for their efficiency and their small plug of space. Therefore, the main objective […]
