Micro T-mixer as a rapid mixing micromixer

Ideal micromixing performance in packed microchannels

“…Ehrfeld et al (1999) fabricated an interdigital micromixer with channel characteristic size of only 25 mm, and the fast mixing was obtained by using the principle of multilamination. Wong et al (2004) demonstrated that the swaying of the fluids in the complicated twisted microchannel caused chaotic advection, hence improved the micromixing performance. The excellent micromixing performance could be achieved by flow splitting, recombination, and rearrangement in split-and-recombine micromixers (Schönfeld et al, 2004).…”

CFD-Based Optimization of a Diamond-Obstacles Inserted Micromixer with Boundary Protrusions

“…For example, Wong et al (2003) performed computer simulations and found that rapid mixing of two liquids can be achieved with the inclusion of boundary protrusion elements at the outlet channel of the cross-shaped micromixer. Wong et al (2004) also observed that the fast mixing can be explained by the asymmetrical flow conditions at the inlets and generation of vortices and secondary flow at the junction only. However, the present study extends to investigate the flow-turning induced vortices around the corners of obstacle and protruded boundaries as well as to perform optimization of the boundary protrusion for mixing enhancement.…”

Design and additive manufacture for flow chemistry

“…79 Mixing within this type of channel design occurs largely via diffusion of the species at the liquid interface, hence mixing efficiency can be relatively low requiring a longer channel design. Mixing efficiency can be improved through the introduction of surface roughness, 80 higher flow rates, 81 and narrowing of the mixing channel. 82…”
