In this thesis, we experimentally study the formation, morphology, dynamics and mass transfer of bubbles flowing through a liquid in a microchannel with a particular emphasis on the behavior and dissolution of CO2 micro-bubbles in high viscosity oils. A significant part of the thesis addresses the initial dynamical behavior of dissolving CO2 monodisperse micro-bubbles in numerous solvents (water, silicone oils, alcohols, alkanes) over a range of flow rates and pressure conditions. The effective mass diffusion flux across the bubble interface is measured by tracking individual bubbles and monitoring their shape as they shrink. The initial steady mass flux is characterized using a practical dissolution coefficient that is shown to depend on the fluids physicochemical properties. Our findings show the possibility to control and exploit the interplay between capillary and mass transfer phenomena in small-scale systems. We also tackle the generation of periodic trains of monodisperse bubbles at the hydrodynamic focusing section of a square microchannel, underlining the hydrodynamics resulting in the bubble breakup under various flow conditions. Finally, we investigate the flow of bubbles in complex microgeometries at large capillary numbers, highlighting the rich variety of flow morphology attainable."},{"label":"dcterms.available","value":"2017-09-20T16:50:18Z"},{"label":"dcterms.contributor","value":"Brouzes, Eric."},{"label":"dcterms.creator","value":"Sauzade, Martin"},{"label":"dcterms.dateAccepted","value":"2017-09-20T16:50:18Z"},{"label":"dcterms.dateSubmitted","value":"2017-09-20T16:50:18Z"},{"label":"dcterms.description","value":"Department of Mechanical Engineering."},{"label":"dcterms.extent","value":"149 pg."},{"label":"dcterms.format","value":"Monograph"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/11401/76453"},{"label":"dcterms.issued","value":"2014-12-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2017-09-20T16:50:18Z (GMT).
