Fluidized bed combustion: mixing and pollutant limitation
TLDR
In this paper, the authors focus on processes in large circulating fluidized bed combustors, and especially on mixing between fuel and air, which is important for combustion but also for sulphur capture through the formation of reducing zones.About:

Preferential concentration of particles by turbulence
John K. Eaton,John R. Fessler +1 more
TL;DR: Preferential concentration describes the accumulation of dense particles within specific regions of the instantaneous turbulence field as mentioned in this paper, which occurs in dilute particle-laden flows with particle time constants of the same order as an appropriately chosen turbulence time scale.

Three-dimensional flow visualization of dilutely dispersed solids in bubbling and circulating fluidized beds
Masayuki Horio,Hiroaki Kuroki +1 more
TL;DR: In this paper, three-dimensional flow structures of dilute suspensions in the freeboard of a bubbling fluidized bed as well as in a circulating fluidised bed of 200 mm internal diameter, roughly a (125-scale model of a commercial boiler, were observed by the laser sheet technique.
