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:

Propagation of the third sound wave in fluid: Hypothesis and theoretical foundation
TL;DR: In this paper, a comprehensive account of the emerging concept of dispersion of heat along the axial direction as a fluid flows through a passage bounded by solid wall has been presented with its most recent and remarkable advancement.

Characterization of a continuous micro-scale pilot unit for petroleum residue hydroconversion with dispersed catalysts: Hydrodynamics and performances in once-through and recycling mode
Tim Jansen,Dimitri Guerry,Delphine Gotteland,Robert Bacaud,Maxime Lacroix,Marie Ropars,Chantal Lorentz,Christophe Geantet,Melaz Tayakout-Fayolle +8 more
TL;DR: In this paper, a continuous micro-pilot unit has been designed to convert petroleum residues with dispersed catalysts, and several operating conditions (residence times and temperatures) have been investigated using the molybdenum naphthenate as catalyst precursor.

Temperature Histories in a UHT Indirect Heat Exchanger
TL;DR: In this paper, an indirect UHT processing system was modeled by a computer program to predict the temperature profile of a mass element of fluid as it progressed through heating, hold and cooling units.

Theoretical Analysis of Heat Integration in a Periodically Operated Cascade of Catalytic Fixed-Bed Reactors
Volker M. Zahn,Michael Mangold,Mykhaylo Krasnyk,Andreas Seidel-Morgenstern,Andreas Seidel-Morgenstern +4 more
TL;DR: In this paper, a simple model based on the assumption of a hypothetical countercurrent of the solid phase is derived and compared with a standard dynamical model of the reactor cascade, and the reduced model describes the limiting case for an infinitely segmented cascade and allows assessment of important properties of the periodic process.

Laminar dispersion in helically coiled tubes of square cross‐section
TL;DR: In this article, the orientation of the cross-sectional plane with respect to the direction of the centrifugal force has been shown to have a significant effect on residence time distribution (RTD) which has been recognized for the first time.

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.
