Micromixers are one of the most crucial components of Lab-On-a-Chip devices with the intention of mixing and dispersion of reagents like small molecules and particles. The challenge facing micromixers is typically insufficient mixing efficiency in basic designs, which results in longer microchannels. Therefore, it is desirable to increase mixing efficiency, in order to decrease mixing length, w...

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...

An effective two-dimensional micromixer named rectangle-square wave micromixer with very simple structure has been presented. The rectangle-square wave micromixer based on split and recombination principle was simulated to analyze the fluid flow and the mixing efficiency. The flow rate, sample concentration, pressure drop at different position in the micromixer was researched. The simulation re...

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...

T This paper reports the mixing performance of an AC electroosmotic micromixer based on the three-dimensional extensional flow generated by a face-to-face, asymmetric pair of planar electrodes. This work represents the first successful use of such an asymmetric electrode pair in an AC electroosmotic micromixer. Due to the highly 3dimentional flow pattern generated by the face-to-face electrode ...

In this study a biophysical passive micromixer with channel anamorphosis in a space of 370 μm, which is shorter than traditional passive micromixers, could be created by mimicing features of vascular flow networks and executed with Reynolds numbers ranging from 1 to 90. Split and recombination (SAR) was the main mixing method for enhancing the convection effect and promoting the mixing performa...
