A numerical model is developed for three-dimensional droplet mixing in serpentine
microchannels with inner-wall ridges (referred to as SMR microchannels). The underlying …

In the present study, a three-dimensional unsteady model is developed via coupling volume-
of-fluid (VOF) method with component transport model to investigate the droplet-based …

The hydrodynamics and mixing process within droplets travelling along a three dimensional
serpentine microchannel are studied using a computational fluid dynamics simulation based …

Mixing is an essential operation in many microfluidic devices. Droplet-based micromixers
utilize droplets for mixing enhancement. In the present study, a novel three-dimensional …

Here, we investigate separately the dependence of the mixing time on the size and velocity
of micro-droplets moving through serpentine channels. We find that the mixing time scales …

In this work we combined numerical simulation with molecular-diffusion effect, high-tempo
micro-particle image velocimetry (μ-PIV), and probability distribution function (PDF) analysis …

When fluids flow in microchannels, due to the relative low hydraulic diameter and low flow
velocity, the flow is usually laminar flow, which hinders the effective mixing between two …

This numerical study was conducted to analyze and understand the parameters that affect
the mixing performance of droplet-based flow in sinusoidal microfluidic channels. Finite …

An effective planar micromixer based on a meandering microchannel with converging–
diverging cross section is proposed, fabricated and investigated in this work. The side walls …

The necessity of microscale mixing processes has been tremendously increasing in most of
the microsize chemical and biochemical devices during recent years, particularly in the …
