Micromixing Performance and Residence Time Distribution in a Miniaturized Magnetic Reactor: Experimental Investigation and Machine Learning Modeling

“…Moreover, correlations for t R /τ R (eq 11) and 1/Pe ax (eq 12) are obtained based on 95% confidence level for guiding mixer design and are in good agreement with the experimental data (Figure S7), where τ R is the theoretical residence time. The parameter ranges for the correlations are 45 < Re < 137, 29 < Re M < 150, 6 10…”

The parameter ranges for the correlations are 45 < Re < 137, 29 < Re M < 150, 6 10 11 demonstrates that the micromixing performance deteriorates significantly with R increase mainly due to longer diffusion distance and higher sensitivity of reaction R2 to the increase of acid concentration. Nevertheless, the rotating flow field exerted by stirrer rotation remarkably improves the mixing quality at extremely high R by rapidly bringing the streams into contact and accelerating the motion of streams.…”

“…5 A narrow RTD is always a prerequisite for obtaining satisfactory yield and selectivity. 6 Micromixing performance, which is usually characterized by competing reaction systems, represents the extent of mixing on the molecular scale. 7 As molecular scale mixing performance has impact on many reaction processes, micromixing could determine whole process cost and product quality especially for many fast reactions.…”

Determination of Liquid Residence Time Characteristics in Spinning Disk Reactors via a Computational Approach

“…A detailed comparison between CFD simulation and experimental methods for RTD determination is shown in Table S1 in the Supporting Information. CFD simulations can achieve the ideal pulse injection by setting extremely short time steps and can monitor the average tracer concentration at any position inside the reactor. , CFD simulation has demonstrated advantages and validity for determining RTD in several rotating reactors, such as RPBs , and rotor–stator high shear mixers, which was estimated to overcome the challenges exposed above and make progress in evaluating the RTD for photochemical reactions in SDRs.…”
