Summary: Magnetohydrodynamic mixing of two fluids in an annular microchannel is modelled as a two-dimensional laminar convection-diffusion problem and examined using asymptotic analysis and numerical simulation. The time \(T\) required for mixing of a plug of solute depends on the Péclet number Pe and on the geometry of the annulus.

An ultrashort mixing length micromixer: The shear superposition micromixer
Lab Chip, 2007We report for the first time a laminar high-performance continuous micromixing process of two fluids over a length of 200 microns in under 10 milliseconds achieved by an optimization of the control parameters amplitude and frequency in the mixing device denoted as 'Shear Superposition Micromixer'.

A novel electrokinetic micromixer
Sensors and Actuators A: Physical, 2004A novel microfluidic mixer based on the modulation of /spl zeta/-potential is proposed and demonstrated successfully. In contrast to previous micromixer work from other groups, this micromixer does not need complex three-dimensional serpentine microstructure or external pumps to generate chaotic advection pulsatile flow.

Electrokinetic Instability Micromixing
Analytical Chemistry, 2001We have developed an electrokinetic process to rapidly stir micro- and nanoliter volume solutions for microfluidic bioanalytical applications. We rapidly stir microflow streams by initiating a flow instability, which we have observed in sinusoidally oscillating, electroosmotic channel flows.

An Optimized Micromixer with Patterned Grooves
2004 International Conference on MEMS, NANO and Smart Systems (ICMENS'04), 2004With the development of microfluidic systems, there is a growing interest in micro scale laminar flow mixing. In this work, the fluid rotating angle and mixing efficiency in a micromixer with patterned grooves are studied as a function of the dimensions of the microstructure by numerical simulation.
