Visualization with pH indicator shows that complete global mixing at the collector by liquid impingement is obtained under our tested conditions. Iodide/iodate reaction shows a rapid mixing at molecular level as the flowrate increases and impingement being enhanced. Micromixing time estimated by IEM (Interaction by Exchange with the Mean) model is compared with other micro-structured mixers in the literature. Comparable mixing performance is obtained using our millimetric reactor with that of micro-structured designs.
The design of multi-channel reactor with arborescent distributor and collector makes possible the numbering-up of multiple channels. Process intensification is highlighted by high throughput and compact size, thus may be attractive for industrial application.
