“…presented numerical results of species concentration distribution in the RPB (Fig. ), indicating that the highest consumption rate of the hydrogen ion and the generation rate of byproducts (I 2 and I 3 − ) showed in the narrow 10 mm region of the inner packing, and the rest of the packings had only a slight influence on micromixing processes, which is consistent with the end effect zone proposed in previous research . The micromixing time calculated from incorporation of the model ranged from 0.05 to 0.3 ms, which is similar to the experimental results.…”

Both experimental and numerical results proved that increasing the rotational speed and liquid flow rate could improve the micromixing efficiency, at least in low viscosity liquid systems.…”

A rotating packed bed (RPB) is one of the cutting‐edge process intensification technologies due to its high mass transfer and mixing efficiency. Nevertheless, owing to the complex structure and hydrodynamic characteristics of RPBs, valuable data inside the reactor is hard to obtain by conventional experimental methods. Computational fluid dynamics (CFD) owing to its unique advantages of low cost, completeness of data and ability to simulate real and ideal conditions, has been adopted by many researchers to carry out fundamental research and practical application of RPBs in recent years. This paper therefore elaborates on the research progress on CFD simulation of RPBs. The building of a physical model of these reactors as well as selection of mathematical models are described, then applicability and accuracy of these models are compared and discussed. Simulation results for gas and multiphase flow in reactors are also presented. Additionally, the application of CFD to mixing and mass transfer between phases and processes in rotating packed beds is introduced. Optimum designs of reactors by the CFD method are also described. Finally, problems remaining with CFD simulation of rotating packed beds and future development directions are discussed. © 2018 Society of Chemical Industry

“…Thus the gas-liquid contacting area sharply increases, which significantly enhances mass transfer processes. Based on 35 years' researches, Higee technology has been widely applied to process intensification and has been proved to be excellent, especially for the processes limited by micro-mixing or mass transfer rate [2][3][4][5][6][7].…”

CFD Modeling of Micromixing and Velocity Distribution in a 1.7‐MHz Tubular Sonoreactor

The effect of high-frequency (1.7 MHz) ultrasound waves on the mixing rate in a new continuous tubular sonoreactor was investigated by CFD modeling. Modeling of piezoelectric transducer (PZT) vibrations was done based on the dynamic mesh model. Results indicate that the acoustic streams were in the direction of wave propagation and their maximum velocity near the PZT surface agreed well with experimental measurements. The micromixing efficiency of the sonoreactor was studied by adopting the Villermaux/Dushman reaction in the modeling. Comparison of the calculated relative segregation index from modeling results with experimental data revealed reasonable accordance.
