Fork-like mixer

Reactor 17 [R 17] Fork-like Chip Micro Mixer-Tube Reactor... 

Central part of this reaction unit is a split-recombine chip micro mixer made of silicon based on a series of fork-like channel segments [32-36]. Standard silicon micro machining was applied to machine these segments into a silicon plate which was irreversibly joined to a silicon top plate by anodic bonding (Figure 4.16).

M 58] [P 53] Air and water were contacted in a five-step fork-like micro mixer [43], Bubbles of 200-500 pm size resulted. The mixing in 10 mixing elements resulted in even smaller bubbles below 100 pm. Coalescence led to the formation of larger bubbles within a few minutes. 

While the multi-lamination micromixers use a parallel approach, the split and recombination units use a linear approach by splitting the flow, recombining it and by rearranging it, almost always with some recirculation flow [60, 63, 65, 66, 84,85]. Designs used to achieve this flow include, but are not limited to, fork-like, ramp-like, cross-like, and curved. Mae et al. reported a two-phase mixer designed to create a water-oil emulsion that could process up to 5 L h (YM-1) and 20 L h (YM-2) [63]. Figure 7.6 shows the YM-1 structure.
