Passive In-Plane Micromixer for Slow Diffusing Liquids
Volume 12: Micro and Nano Systems, Parts A and B, 2009The problem of passive micromixing has been analyzed. Laminar flow in microchannels implies that transport processes including mass transfer are dominated by diffusion; inertial effects and have little to no effect on mixing in small scale conduits. Study of the diffusion theory shows that the velocity at the interface of fluids intended to be mixed is

Design and simulation of passive micromixers based on capillary
Microfluidics and Nanofluidics, 2012Three-dimensional passive micromixers made by clamping capillaries in different directions and angles are presented in this paper. This type of mixers is easier to fabricate than the multi-layer passive mixers, and is the firstly proposed capillary-based micromixer.

Passive Vortex Micromixers Utilizing Hybrid Laminations
Volume 13: Nano-Manufacturing Technology; and Micro and Nano Systems, Parts A and B, 2008This theoretical investigation analyzed the three-dimensional momentum and mass transfer characteristics arising from the multiple inlets and single outlet in micro chamber which consists of a right square prism, an octagonal prism or a cylinder. The effects of various geometric parameters, inlet velocities, and the types of lamination on the mixing ...

Numerical optimization of passive chaotic micromixers
2012Due to the lack of turbulence in micromixers diffusion is the main process contributing to microfluidic mixing. Especially mixing of uids with low diffusivity is a difficult task. The recently discovered mechanism of "chaotic-advection" enhances the diffusion process by stretching and folding the fluid interfaces in order to provide a larger interface.
