Design and evaluation of an easily fabricated micromixer with three-dimensional periodic perturbation

An effective splitting-and-recombination micromixer with self-rotated contact surface for wide Reynolds number range applications

“…The value of r s ranges from 0 for no mixing or diffusion to 1 for perfect mixing. Before performing the simulation, mesh independency tests 27,44 for these three models are made to determine the suitable number of elements. Take the XH model, for example; five different structured tetrahedral grid systems with an element number ranging from 2.8 Â 10 4 to 5.03 Â 10 5 were tested, as shown in Fig.…”

Numerical analysis of lamination effect in a vortex micro T-mixer with non-aligned inputs

“…The results showed that if the flows are not fully developed at the micro mixer confluence, the engulfment phenomenon occurs at the high Reynolds numbers that causes the different flow pattern as well as the considerable reduction of mixing performance compared to the case that incoming flows are fully developed. Lin et al [13] used a new design of passive micro mixer for micro chemical application. In this design, the path of micromixer flow is distinguished by the combination of square wave structure and periodic cubic grooves.…”

Numerical characterization of simple three-dimensional chaotic micromixers

“…A large number of studies illustrated the obstacles or grooves on channel walls can result in rotating transversal flows and further good mixing [16][17][18]. Such a simple design was even applied to combine with a two-dimensional serpentine microchannel for developing new efficient micromixers [19][20][21].…”
