Multiphase microflow network

For many chemical processing applications, microchemical systems should include solvent extraction and interfacial reaction components utilizing both aqueous and organic (or gas and liquid) solutions. Both solutions must be controlled to realize general chemistry in a microchip. In 1990s, electroosmotic flow was used in microchip electrophoresis (Auroux et al., 2002 Reyes et al., 2002) however, the electroosmotic flow is restricted to the flow control of only one type solution (aqueous buffer). Therefore, electroosmotic flow is not suitable for a flow-control method to

Ranking the importance of different forces helps in categorizing the increasing number of experimental studies with the ultimate goal to predid multiphase flow behavior in microchannel networks and formulate guidelines for their design. Multiphase microflows are charaderized by the ratio of viscous to surface forces, the capillary number (Co) and by the ratio of fluid viscosities ...
