Theoretical search for solutions to minimize negative influence of segregation in mixing of particulate solids
TL;DR: In this paper, a non-linear Markov chain model for the mixing of segregating components is proposed, and the optimal solutions are obtained by controlling the particle flow outside the mixing operating volume while the components are being loaded, modifying particle circulation inside the mixing zone during the process, and by structuring the load in the mix zone.

Mathematical modeling of manganese adsorption onto bone char in a continuous fixed bed column incorporating backmixing and shriking core approaches
TL;DR: In this paper, the authors investigated the dynamics of manganese adsorption onto bone char in a continuous fixed bed column using a mathematical model that incorporates: (i) the backmixing model to describe the fluid flow through the bed and (ii) the shrinking core model within spherical adsorbent particles.

Traitement par une méthode d'éléments finis de modèles de colonnes de rectification discontinue à garnissage
TL;DR: In this paper, a mathematical model representing several operating modes of a packed batch distillation column is presented, including axial and radial dispersion phenomena, and the equations are solved by a finite element method based on the Galerkin criterion, and also by using a finite difference procedure.

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.
