A numerical study of 3D electrokinetic flows through micromixers was performed. The micromixers considered here consisted of heterogeneous rectangular microchannels with prescribed patterns of zeta-potential at their walls. Numerical simulation of electroosmotic flows within heterogeneous channels requires solution of the Navier-Stokes, Ernest-Plank and species concentration equations. It is kn...

Abstract A dynamic mixing model for a microfluidic platform that uses bending and twisting characteristic is proposed in this work. The action of on efficient the microchannel tested using Navier-Stokes equations. Micromixers being broadly applied micro total analysis systems (µTAS). Passive micromixers are largely preferred from their heftiness, serenity amalgamation cost effective. However ra...

Due to high mixing performance and simple geometry structure, serpentine micromixer is one typical passive that has been widely investigated. Traditional zigzag square-wave micromixers can achieve sufficient mixing, but tend induce significant pressure drop. The excessive drop means more energy consumption, which leads low cost-performance of mixing. To mitigate drop, a novel utilizing ellipse ...

numerical investigation of 3d electrokinetic mixing through micromixer has performed both qualitatively and quantitatively. in order to reduce numerical expenses of 3d flows, we implement the helmholtz-smoluchowski method for the numerical modeling of electroosmotic flows. according to the previous study of electrokinetic mixing inside the heterogeneous microchannels, existence of the vortexes ...

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...
