Enhancing Mixing Efficiency: A CFD-Driven Design of a Helical Pipe-Type Motionless Mixer with a Kenics-Type Element
An approach to process intensification is the use of motionless mixers. Among various motionless mixers, the helical pipe-type motionless mixer has attracted considerable attention. However, its mixing performance can vary greatly depending on the location of raw material injection. In this study, we developed a helical pipe-type motionless mixer that provides consistent mixing performance regardless of the injection position of the raw materials. This helical pipe-type motionless mixer has only one Kenics-type element in the center of the helical pipe. The mixing performance of this design was evaluated using computational fluid dynamics (CFD). The mixing performance was evaluated using the mixing coefficient Mc defined as an indicator of mixing efficiency between two liquids. The Mc for the helical pipe-type motionless mixer without elements has at most 0.5. However, the results showed that the helical pipe-type motionless mixer having more than 4 turns with one Kenics-type element resulted in \({M}_{c}\ge 0.95\) in the region where Reynolds number was greater than 30.
期刊介绍:
The Korean Journal of Chemical Engineering provides a global forum for the dissemination of research in chemical engineering. The Journal publishes significant research results obtained in the Asia-Pacific region, and simultaneously introduces recent technical progress made in other areas of the world to this region. Submitted research papers must be of potential industrial significance and specifically concerned with chemical engineering. The editors will give preference to papers having a clearly stated practical scope and applicability in the areas of chemical engineering, and to those where new theoretical concepts are supported by new experimental details. The Journal also regularly publishes featured reviews on emerging and industrially important subjects of chemical engineering as well as selected papers presented at international conferences on the subjects.
