This study demonstrates that flowrate, number of channels, hydrodynamic resistances, and phase ratio have a significant impact on the maldistribution in parallel microfluidic reactors. Advanced statistical methods, such as Multivariate Analysis of Variance (MANOVA), can provide additional insights and partially compensate for variability between experiments.
Present parametric study shows that the flowrate, number of channels, hydrodynamic resistances and phase ratio significantly affect the maldistribution in parallel microfluidic reactors (i.e., numbering-up). Especially the effect of flow rate and phase ratio has not been reported before. However, these findings are of a qualitative nature due to a high degree of variability between experiments. Additional experiments show that the stable point of operation easily shifts in the considered set-ups, explaining this variability. Therefore, a Multivariate Analysis of Variance (MANOVA) in SPSS is introduced to partially compensate for this variance and, also, manage the large data set that results from a parametric study. It is shown that introducing advanced statistical methods can provide additional insights and can further push the field of numbering-up. (C) 2022 Institution of Chemical Engineers.
