A rapid micro-mixer/reactor based on arrays of spatially impinging micro-jets

摘要

We present a novel micro-mixer/reactor based on arrays of spatially impinging micro-jets. Using the impinging plumes from two opposite arrays of micro-nozzles, the interfacial contact in the mixing chamber was significantly boosted. This effect has effectively increased the mixing efficiency. The micro-mixer/reactor presented in this paper has a very simple structure and was fabricated using a technology based on UV lithography of SU-8 resist. The experimental results of the prototype mixers have proved the high mixing efficiency with a pressure drop of about 200 Pa. This micro-mixer/reactor can be easily integrated with other micro-fluidic components and used in various biochemical, biological and chemical systems.
