Design of Efficient Electroosmotic Micromixer

Micro-bio/chemical applications in a μTAS (Micro Total Analysis Systems) require rapid and uniform mixing of a number of fluid streams that carries bio/chemical species in the solution. An electro osmotic mixer from COMSOL model library is taken as a main model from which other alterations are designed for optimization. The circular, square and elliptical mixers were modeled to see the variation in the mixing. We analyzed the mixing process by varying the mixing shape, concentration, mixing channel width and electrode pairs. Concentration variance at the outlet over time was studied to determine the extent of mixing.
