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:

Mass transport enhancement in direct formic acid fuel cell with a novel channel design
TL;DR: In this article , the authors used computational fluid dynamics modeling to identify fuel starvation zones and uneven formic acid concentration distribution at the reaction surface in the DFAFC system with a standard channel design with serpentine arrangement.

Hydrodynamic studies on two multistage mixer‐settlers
C. Hanson,M. Sharif,M. Sharif +2 more
TL;DR: In this paper, a relationship between perfect mixing and perfect plug flow is developed to describe the flow pattern of mixer-settlers and various parameters are evaluated for the two units studied.

The effect of the level of micromixing on the optimal design of cstr's performing michaëlis-menten reactions
TL;DR: In this article, the authors emphasized the industrial application of enzymes for the catalysis of a great number of reactions within the food, medicine, and pharmaceutical domain. And they showed that enzymes are remarkable catalysts in three major aspects: E activity, specificity, and versatility.

Flow Characteristics of Reactors—Flow Modeling
TL;DR: In this article, the cumulative distribution function and the residence time distribution functions used to characterize nonideal flow in reactors are introduced, and their determination from step and impulse responses in tracer experiments is established using the convolution formula that relates the output of a tracer experiment to an arbitrary input.

Comparison of Different Methods for Evaluating the Hydraulics of a Pilot-Scale Upflow Anaerobic Sludge Blanket Reactor
TL;DR: In this article, the tracer was collected at two points: in the effluent and in the sludge blanket and the results obtained show that the lack of criteria for defining the flow inside the reactor (plug flow, dispersed-flow or complete-mix flow) yields inconsistencies in methods (i) and (iii).

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.
