Mixing Enhancement of a Passive Micromixer with Submerged Structures

Micromachines, 2022
A passive micromixer combined with two different mixing units was designed by submerging planar structures, and its mixing performance was simulated over a wider range of the Reynolds numbers from 0.1 to 80. The two submerged structures are a Norman window and rectangular baffles.
