Mass and heat transfer enhancement by a novel mixer with triangular-notched rectangular baffles for continuous flow chemical process

Abstract

Mass transfer efficiency, heat transfer efficiency, and treatment capacity play important roles in the continuous flow chemical process. To enhance the continuous flow chemical process, a novel mixer with triangular-notched rectangular baffles structure was designed and optimized. The performance of mixers was characterized by a comprehensive computational fluid dynamics (CFD) method that couples heat and mass transfer. The results show that the optimized mixer has a maximum increase of 4.25 times in mixing efficiency and 83.8% in heat transfer compared with 10 mm mixer without baffles structure. Furthermore, the scale of the mixer with triangular-notched rectangular baffles structures was enlarged to 25 mm under the premise of ensuring high mass and heat transfer efficiency, low-pressure drop and high treatment capacity. This study provides a scale-up strategy for continuous flow chemical process enhancement.
