Investıgatıon ac elektro-ozmotik akış tabanlı mikro tellerle sağlanan mikro akışkan karıştırıcının incelenmesi

AC electrokinetics (ACEK) is useful technique for providing species manipulation and liquid transportation. This method is applicable to many elds like cell separation, synthesis, pumping, mixing in microfuidics technologies. Mixing in micro-scale is very problematic issue due to the domination of surface forces over inertial forces. For acquiring complete mixing, extended channels or longer time is needed. To accelerate mixing, active and passive micromixers are presented in the literature. Among active micromixer types, ACEK-based micromixers are preferred techniques due to their advances in preventing electrochemical reactions and electrolysis. In this thesis, micromixer based on AC electroosmosis (ACEO) around micro rods is introduced. In this study, mixer performance is evaluated according to variable rod con gurations, two different surface material and flow rates. Both computational modeling and experimentation are handled. Easy and cheap fabrication with commercially available metal wires is adopted. By introducing 3D electrode pairs, 3D vortex pro le is presented and the most infuential con guration is discovered.
