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 […]

Gas/liquid mass transfer in Technicolor

Tuesday 10th April 2012, UBC, room CHBE 102, VANCOUVER, CANADA Mass transfer in gas/liquid systems is of prime interest for several areas (medicine, chemicalengineering, environmental purpose, waste water treatment, etc.). Some techniques enable a directvisualization of this complex phenomenon and thus represent a powerful tool for understanding thedifferent mechanisms governing the mass transfer. The purpose […]
