Manifold split-and-recombination micromixer

Manifold split-and-recombination micromixers are also popular and powerful micromixers. " In this type of micromixer, two solutions to be mixed are introduced into a channel and combined. Then, the mixture is split into two streams in such a way that each stream contains segments of two different solutions. The two streams are then introduced into the next channel and recombined so that the number of solution segments increases, as shown in Figure 7.10. 

The Toray Hi-mixer is a special type of manifold split-and-recombination micromixer. The structure of the Hi-mixer is shown Figure 7.12. In the Hi-mixer, when two layers of the solutions enter the mixing element, they are split into eight layers by using twist walls in the element. Therefore, in this method, the number of layers increases exponentially by repeating the operation (4" after the wth iteration).
