Fabrication of Micromixers Utilizing Shedding Effect Induced by Electrokinetic Instability

Mixing enhancement by utilizing electrokinetic instability in different Y-shaped microchannels

An experimental study was conducted to assess the effectiveness of manipulating convective electrokinetic instability (EKI) waves to control/enhance fluid mixing inside three Y-shaped microchannels, which includes a conventional straight channel, a channel with micro-cavities, and a channel with microsteps. Epi-fluoresence imaging technique was used to conduct qualitative flow visualization and...

A model for laminar diffusion-based complex electrokinetic passive micromixers.

This paper presents a model for the efficient and accurate simulations of laminar diffusion-based complex electrokinetic passive micromixers by representing them as a system of mixing elements of relatively simple geometry. Parameterized and analytical models for such elements are obtained, which hold for general sample concentration profiles and arbitrary flow ratios at the element inlet. A lu...

Residence Time Control in Micromixers with Vortex Shedding

Residence time control is an important indicator of micromixer design. When using vortex shedding to enhance mixing efficiency in a micromixer, the relationship between residence time and vortex shedding becomes important; if residence time is shorter than shedding time, the fluid elements flow through the channel too quickly with no contribution of vortex shedding to mixing. Both residence tim...
