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:

Performance of tapered column packed-bed bioreactor for ethanol production.
Haluk Hamamci,Dewey D. Y. Ryu +1 more
TL;DR: The tapered column bioreactor system showed a much better flow pattern of gas and liquid phases within the reactor, thereby providing a more homogeneous distribution of gas–liquid–solid phases in the reactor without any phase separation.

Modeling of evacuated pulse micro-reactors
TL;DR: In this paper, the effect of the inlet section on the response of a packed-bed micro-reactor is illustrated and quantified, and a simple boundary condition of zero exit concentration is justified.

Mathematics in chemical engineering: A 50 year introspection
TL;DR: A review of the role of mathematics in the field of chemical engineering in the latter half of the twentieth century is given in this article, concluding that mathematics is the main medium to meditate not only about processes, but also about materials and products.

Assessing the homogeneity of powder mixtures by on-line electrical capacitance
TL;DR: In this article, a two-electrode electrical capacitance method is used to measure the permittivity of mixtures while flowing in a 1-D set up, and an emphasis is placed on the possibility of following homogeneity evolution through permitivity measurement, without the necessity to calculate the volumetric proportions of each component from an effective medium formulation.

Insignificant role of hydrodynamic dispersion on bacterial transport
Kenneth M. Unice,Bruce E. Logan +1 more
TL;DR: It is concluded that dispersion can be neglected in calculating particle collision efficiencies in both laboratory and field experiments.

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.
