| Research Abstract |
The following results were clarified with this study about flow controls in micro channels utilizing aqueous polymer solutions: (1) the behaviors of the polymers were influenced with the gap size in the micro channels. (2) Flow rates of aqueous polyelectrolyte solutions were controlled using ion strength conditioning system. (3) Effective mixing in micro channels was obtained utilizing unstable vortexes generated with the polymer solutions. Moreover, we have found that (4) particle mixing was encouraged by applying electric fields from numerical simulation.
