A novel passive micromixer model computational analysis with twist and bend

Abstract

Abstract A dynamic mixing model for a microfluidic platform that uses bending and twisting characteristic is proposed in this work. The action of twisting and bending on mixing efficient in the microchannel is tested using Navier-Stokes equations. Micromixers being broadly applied in micro total analysis systems (µTAS). Passive micromixers are largely preferred from their heftiness, serenity of amalgamation and cost effective. However rapid mixing in this model is difficult but can be achieved with a twist in the model and offset. From the past study, we know that with a high Reynolds number mixing efficiency effectively improved. Chaotic advection allows the micromixer model to generate secondary flow which led to a drop in high-pressure drop in the model.
