Abstract
A numerical study of a novel high performance micromixer is presented, which creates a complex three dimensional fluid flow field in a straight microchannel through the use of non-uniform zeta potential surface on microchannel walls, without the need for complex geometries and fabrication processes, or unsteady flow actuation. By patterning the non-uniform zeta potential surfaces with sloped interface against the net flow direction, transverse velocity components and vortical structures are induced, both are highly desirable for mixing.
