Considerations on the design of flow cells in by-pass systems for process analytical applications and its influence on the flow profile using NMR and CFD
TL;DR: In this article, the design of sample flow cells, commonly used in on-line analytics and especially for medium resolution NMR spectroscopy (MR-NMR) in low magnetic fields, was experimentally and theoretically investigated by 1H NMR and numerical simulations.

Discrete element method simulation of a conical screen mill: A continuous dry coating device
TL;DR: In this article, the authors examined the influence of the operating parameters of a conical screen mill on the residence time distribution (RTD) and mean residence time (MRT) of powder dry coating and the relationship between average collision number (ACN), number of particles inside the transition zone (region above the conical part), and MRT.

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.
