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:

Defining and measuring the mean residence time of lateral surface transient storage zones in small streams
TL;DR: In this article, the authors studied mean residence time of lateral STS in small streams over Reynolds numbers (Re) 5000-200,000 and STS width to length (W/L) aspect ratios between 0.2-0.75.

New ventilation index for evaluating imperfect mixing conditions – Analysis of Net Escape Velocity based on RANS approach
TL;DR: The concentration of contaminant in a room is not always uniformly distributed and hence it is important to evaluate the ventilation efficiency at various points or domains in the room to optimize the room ventilation efficiency.

Batch and continuous spouted bed drying of cereal grains: The thermal equilibrium model
TL;DR: In this paper, a complete set of equations with no adjustable parameters are written for numerically predicting the variation of grain temperature and moisture content with time for batch drying of well mixed deep beds of three cereal grains, as well as the exit grain and air moisture contents and temperatures for continuous drying.

Measurement of the heat transfer coefficient in plate heat exchangers using a temperature oscillation technique
TL;DR: In this paper, a mathematical model with axial dispersion has been used to evaluate heat transfer coefficient and dispersion coefficients characterised by NTU and Peclet number, respectively, and the experimental results obtained by using the temperature oscillation technique have been compared with those obtained by traditional steady state experiment.

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.
