Abstract
Numerical analysis and mixing experiments have been performed to investigate that the mixing performance of SAR micromixers with E-shape mixing units has a huge advantage than traditional micromixers (such as T micromixer). In this paper, an excellent mixing efficiency can be achieved by splitting-recombination and chaotic advection mechanisms. The results indicate that when the Reynolds number increases from 0.5 to 15, the mixing efficiency of two micromixers decreases. And at Re = 15, the lowest mixing efficiency of SAR micromixer is 60%. When the Reynolds number increases from 15 to 80, the mixing efficiency of SAR micromixer reaches about 94%. On the country, the mixing efficiency of T micromixer continues to decrease.
