Investigation of mixing in a cross-shaped micromixer with static mixing elements for reaction kinetics studies

Fast Fabrication Process of Microfluidic Devices Based on Cyclic Olefin Copolymer

“…These three mixers designs fabricated were a classical T-shaped mixer, a T-shaped mixer with a zigzag shaped channel [22], Fig. 1(a), and a T-shaped mixer with additional obstacles on the wall [23], see Fig. 1(b).…”

Surface-enhanced Raman scattering microfluidic sensor

“…To obtain an efficient mixing, a miniaturized microfluidic device with special geometrical features should be designed for the generation of repeated mixing flow patterns, which will result in chaotic advection and therefore effective mixing. Many different types of passive micromixers, such as branching channel, 25 three-dimensional C-shape channel, 26 pillar array channel, 27 and serpentine-shaped channel such as groove-shaped, 28 obstacles on the channel's wall, 29 modified Tesla 26 and zigzag-shaped channels 30 have been reported for the fast and efficient mixing of two confluent streams. Recently, a high density pillar obstruction poly(dimethylsiloxane) (PDMS) microfluidic mixer was fabricated and estimated the mixing behavior of confluent streams of three different sets of miscible solutions using a fluorescence microscope.…”

Biometric application in fuel cells and micro-mixers

“…Another type of passive mixer is the lamination mixer, which decreases the diffusion length and increases the contact area of fluids by splitting incoming streams into multiple substreams, and then laminating them into one stream again (Kamholz and Yager, 2002). Concerning the most traditional passive micro-mixers, they have been constructed with straight fluid channels and designed with a combination of fillisters and/or fold paths to enhance the mixing effect (Wong et al, 2003). However, the design of a straight channel requires a longer length to achieve the goal of uniform mixing.…”
