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:

TL;DR: In this paper, a 3D model of transient tracer transport was developed based on the flow model to predict bioreactor residence time distribution (RTD), which was validated in terms of RTD against tracer experiments performed with commercial scaffolds for bone tissue engineering.

Asymptotic Analysis of Three-Scale Model of pH-Dependent Flows in 1:1 Clays with Danckwerts’ Boundary Conditions
TL;DR: In this article, the electroremediation process is modeled as a coupled system of nonlinear partial differential equations and analytical solutions of the macroscopic equations are derived considering the asymptotic behavior of strongly convective and diffusive regimes.

Lattice-Boltzmann Simulation of Lipase Separation via Bioaffinity Chromatography: Imposing Dirichlet or Danckwerts Inlet Condition☆
TL;DR: In this paper, a dynamic 1-D model was adopted comprising Langmuir adsorption-desorption kinetics and convective-diffusive transport, and particle distribution functions were assigned to adsorbate concentrations in fluid and solid phases.

Dimensionless analysis of the flow of spherical particles in two-phase flow in straight tubes
TL;DR: In this paper, the authors measured the linear and rotational velocities of individual spherical particles in transparent 2-m long straight tubes and correlated them with generalized Reynolds, Archimedes and Froude numbers.

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.
