Experimental verification of the scaling laws for CFB boilers of different designs

open access: yesChemical and Process Engineering, 2016
In the paper flow dynamic similarity criteria have been presented to reflect the macroscopic flow pattern in the combustion chamber of large-scale circulating fluidised bed boilers.

Applications of Electrical Capacitance Tomography for Research on Phenomena Occurring in the Fluidised Bed Reactors

open access: yesChemical and Process Engineering, 2014
The paper presents a review of current achievements in the Electrical Capacitance Tomography (ECT) in relation to its possible applications in the study of phenomena occurring in fluidised bed reactors.

Mechanism of charge transfer in the discontinuous metal phase of a fluidized bed electrode [PDF]

open access: yes, 1977
From measurements of double layer capacity, collision frequency and contact time during collision, it is concluded that models for charge transfer in the discontinuous phase of fluidized bed electrode that are based on ideal particulate fluidization ...

Segment tip geometry of sheet intrusions, II: Field observations of tip geometries and a model for evolving emplacement mechanisms

open access: yesVolcanica, 2021
Igneous sheet intrusions are segmented across several orders of magnitude, with segment tip geometry commonly considered indicative of the propagation mechanism (brittle or non-brittle). Proposed propagation mechanisms are inferred to represent host rock

Modes of wall induced granular crystallisation in vibrational packing [PDF]

open access: yes, 2018
Granular crystallisation is an important phenomenon whereby ordered packing structures form in granular matter under vibration. However, compared with the well-developed principles of crystallisation at the atomic scale, crystallisation in granular ...

The Influence of Operating Parameters on Adsorption/Desorption Characteristics and Performance of the Fluidised Desiccant Cooler

open access: yesEnergies, 2018
This paper concerns the issue of the proper selection of the operating parameters of the fluidised desiccant cooler. Despite the fact that fluidised desiccant cooling technology is being reported in the literature as an efficient way to provide cooling ...

Journey of an intruder through the fluidisation and jamming transitions of a dense granular media

open access: yes, 2009
We study experimentally the motion of an intruder dragged into an amorphous monolayer of horizontally vibrated grains at high packing fractions. This motion exhibits two transitions.

Investigation of the effect of consolidation on cement flow behaviour [PDF]

open access: yes, 2020
International audienceOne of the main problems affecting the flow of cement bulk powder is the formation of cohesive arching at the outlet of the hopper, causing blockage of the silo opening and bridge formation.

Fluidisation as a feeding mechanism in beach flies [PDF]

open access: yesNature, 1974
WE have seen groups of small (4–5 mm long) grey flies belonging to the species Lipochaeta slossonae Coquillett, 1896, standing, shaking and apparently feeding, or flying for short distances on stretches of wet sandy beach in La Jolla, California and San Felipe, Mexico.
