A Review of Techniques for the Process Intensification of Fluidized Bed Reactors
TL;DR: In this article, the authors review modification techniques for fluidized beds from the perspective of the principles of process intensification (PI), that is, effective bubbling suppression and elutriation control.

Particle volumetric residence time calculations in arterial geometries.
TL;DR: The utility of the VRT concept for cardiovascular studies, particularly if a subpopulation of all particles is to be tracked, is demonstrated, and it is concluded that the volumetric residence time is a useful tool.

Perturbative theory of the packing of mixtures and of non-spherical particles
R.B.S. Oakeshott,Sam F. Edwards +1 more
TL;DR: In this article, a simple theory for the packing of irregular particles and mixtures considered as a perturbation of a packing of monodisperse spheres is presented. But this theory assumes that the irregular particles are of different shapes and sizes.

On models of granular material flow under dynamic conditions
TL;DR: In this paper, a system of hard smooth, nearly elastic spherical particles is considered as a model of granular material flowing under dynamic conditions, i.e., when particle inertia is responsible for the transfer of momentum in the material.

The influence of operating variables on the residence time distribution for material transport in a continuous rotary drum
TL;DR: In this article, the influence of operating variables on the mean and variance of the residence time distribution for material transport in a continuous rotary drum is described and an approximate form of the exact solution to the axial dispersion model for an impulse input is provided.

The residence time of solids in gas-fluidized beds
TL;DR: A critical survey of the different models proposed for solids transport in gas-fluidized beds is given in this paper, where it is shown that many of the models can fit the residence time distribution curve (the F t -t curve) fairly well despite the fact that the physical behaviour of the bed is not recognized in these models.

Residence time distribution of solids in multistage fluidisation
TL;DR: In this paper, the residence time distribution of the solids in multistage fluidisation, wherein downcomers for transferring solids from stage to stage are provided to the horizontal perforated plates, is experimentally investigated covering a wide range in process variables using flat, baffle and spiral plates developed in the study.
