Abstract

In this study, a variant of 3D split-and-recombine micromixer is proposed for enhanced micromixing. The mixing analysis was carried out for water and blood flows through the three-dimensional numerical model. The blood flow was modeled using several non-Newtonian fluid models existed in the literature and performance was compared for mixing index. Further, the performance of the proposed micromixer was compared with several other designs of micromixers available in the open literature for a wide range of Reynolds numbers covering diffusion, transient, and advection-dominated flow regimes. Finally, Carreau-Yasuda model was used to carry out parametric analysis of the proposed micromixer for mixing index.
