TLDR
In this article, the authors proposed a method to predict the distribution of residence-times in large systems by using distribution-functions for residencetimes, which can be used to calculate the etficiencies of reactors and blenders.About:

Predicting the performance of immobilized enzyme reactors using reversible Michaelis–Menten kinetics
TL;DR: A general mathematical model is developed for predicting the steady state performance of immobilized enzyme reactor performing reversible Michaelis - Menten kinetics, taking into account the effect of external diffusional limitations, the axial dispersion and the equilibrium constant on reactor performance quantified as relative substrate conversion and yield.

Model and experimental study of relationship between solid fraction and back-mixing in a fluidized bed
TL;DR: In this article, the relationship between time-average solids fraction and back-mixing behavior has been carefully investigated by experimental and model study, and the results indicate that dense solid phase can decrease the potential energy barrier of back-ward jump against main flow.

Volatile tracer dispersion in multi-phase packed beds
Nathalie Márquez,M. Musterd,Pedro Castaño,Rob J. Berger,Jacob A. Moulijn,Michiel Makkee,Michiel T. Kreutzer +6 more
TL;DR: In this article, the effect of volatility on residence time distribution and conversion in multiphase reactors was analyzed using two mobile zones, one for the liquid phase and the other for the gas phase, with dispersion in each zone and mutual mass transfer.

The Definition and Measurement of Some Characteristics of Mixtures
TL;DR: In this paper, it is shown that the important features of such mixtures can be expressed by two statistically defined quantities, the scale and the intensity of segregation, and methods of measuring these are suggested.
