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:

An efficient method for solving two-point boundary value problems with extremely high accuracy
TL;DR: A two-point boundary value problem associated with an immobilized enzyme reaction was investigated as a model system, and it was found that the accuracy of numerical solutions obtained by the proposed method was almost the same as the accuracies of the computer.

Measurement and modeling of residence time distribution of overflow ball mill in continuous closed circuit
TL;DR: In this paper, the shape of the residence time distribution (RTD) curves of a primary ball mill operating at two feed rates (i.e., 280 and 230 tons per hour (t/h)) was analyzed using tracer technique.

The use of momentum ratio to evaluate the performance of CSTRs
TL;DR: In this paper, the residence time distribution of a CSTR was measured and analyzed for variations in CSTR feed geometry, impeller speed and inlet flow rate, and the measured residence time distributions were also used to characterise the degree of plug flow behaviour and shortcircuiting.

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.
