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:

An oscillating baffle column fitted with stator rings I. Theoretical model for a counter-current extraction column
W. J. Thomas,P. K. J. Weng +1 more
TL;DR: In this paper, a modified form of an oscillating baffle column was introduced in which horizontal stator rings are introduced and a theoretical technique was described for establishing true values for the number of transfer units for the continuous phase and disperse phase, NTUc and NTUd.

Application of Danckwerts-type boundary conditions to the modeling of the thermal behavior of metal hydride reactors
Chakkrit Na Ranong,Gustavo A. Lozano,Jobst Hapke,Wilfried Roetzel,Georg Fieg,José M. Bellosta von Colbe +5 more
TL;DR: In this paper, a model-based investigation of a metal hydride reactor applied as a solid state hydrogen storage device is presented, where the interface between porous and non-porous regions is a discontinuity with respect to energy transport mechanisms.
Improved Standpipe Entrance for Stable High-Flux Flow
TL;DR: In this article, the mixing pattern of a tracer particle which simulates a fuel particle is studied in a cold 2-dimensional fluidized bed with respect to the influence of fluidization velocity, bed height, tracer particles size and air-distributor pressure drop under conditions typical for bubbling liquidized bed boilers.

Probability theory for inverse diffusion: Extracting the transport/kinetic time-dependence from transient experiments
M. Ross Kunz,Rakesh Batchu,Yixiao Wang,Zongtang Fang,Gregory S. Yablonsky,Denis Constales,James Pittman,Rebecca Fushimi +7 more
TL;DR: The proposed residence time distribution for the TAP reactor, and the following algorithm referred to as the G-Procedure, is shown to measure time-dependent rate and concentration information in the active zone of the reactor while being mechanistic and diffusional model free.

Modeling of the maleic anhydride circulating fluidized bed reactor
Pranava Chaudhari,Sanjeev Garg +1 more
TL;DR: A simple reactor model with suitable hydrodynamic and kinetic models at the operating conditions of both the pilot and commercial MA CFB reactors is proposed and simultaneously minimizes the total bias based on the individual biases for each component of the multi component reactor system and the total error in a multi-objective framework.

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.
