Performance Investigation of Micromixer with Spiral Pattern on the Cylindrical Chamber Side Wall

In this paper, a sequence of passive micromixers with spiral patterns on the side wall cylindrical chambers are designed, optimized, prepared and tested. The simulation studies show that vortex magnitude continuity in mixing chamber most important factors to determine performance, while inlet position structural parameters secondary influences their performance. According above principles, performance micromixer continuous sidewall finally wins out. total length is only 14 mm, but when Re = 5, index can reach 99.81%. multi-view visual tests these mixer chips by 3D printing consistent results. This paper provides new idea for optimizing problems floor area pressure loss significantly improved compared conventional structure.
