Modeling bimolecular reactions and transport in porous media via particle tracking
TL;DR: In this article, a particle tracking method was used to simulate several one-dimensional bimolecular reactive transport experiments, where the reactants are represented by particles and the particle/particle reactions are determined by a combination of two probabilities dictated by the physics of transport and energetics of reaction.

SCRAPED SURFACE HEAT EXCHANGERS.: A literature survey of flow patterns, mixing effects, residence time distribution, heat transfer and power requirements.
TL;DR: In this article, a survey of flow patterns, mixing effects, heat transfer and power required for rotation in scraped surface heat exchangers (SSHE) is thoroughly discussed, with the emphasis on assumptions and results, while the principal design of different SSHEs are only briefly discussed.

On modelling, monitoring and control of fixed bed bioreactors
TL;DR: In this paper, the authors propose a control algorithm for fixed bed bioreactors which are based on the nonlinear distributed parameter model of the process and analyze the influence of the position of the internal sensors on the observability in order to determine the best observability possible in practice.

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.
