Fluidised beds as ‘coolth’ stores
Applied Energy, 1991Abstract High energy-density thermal storage at low temperatures is feasible using phase-change materials. Thus an energy-storage device has been conceived which uses water-absorbing cross-linked polymers, known as hydrophilic materials. These were produced in the form of particles, which can be hydrated.

Circulating fluidised-bed combustion
Applied Energy, 1990Abstract A mathematical model for the steady-state combustion of char in a circulating fluidised bed (CFB) has been developed by taking into account the bed's hydrodynamic conditions, chemical-reaction rates, and combustion mechanism and the conservation of mass and energy. The model is an improvement over the simplified combustion model developed by

Flow patterns in fluidised beds
Rheologica Acta, 1965The characteristics of the behaviour of the particles in a liquid fluidised bed in which the influence of the bubbles of fluid is small, depends at a particular liquid flowrate, on the size and size range of the particles.

The theory of fluidised bed coating
The Chemical Engineering Journal, 1970Abstract A general theory is presented to predict the rate of coating in a fluidised bed of polymer powders. The relations derived give the coating thickness as a function of residence time of the object in the bed, the thermal and the physical properties of the object, the gas flow rate, i.e.

Developments in fluidised-bed technologies
Applied Energy, 1988Conventional mobile-particle beds have been developed in order to store heat (or cold) for satisfying industrial and/or air-conditioning requirements by the use of thermally-active particles in which the principal storage mechanism is latent heat. Also fluidisation has been achieved, both in air and in high vacua, using ultrasonic stimulation.

Fluidised bed combustion (FBC) differs from both conventional stokers and pulverised fuel combustion in being applicable to a wide spectrum of modern coal-fired systems ranging from small industrial boilers and furnaces to large power generation units.

Powder Technology, 1967
The paper begins by summarising theory and experimental data concerning the rate of rise of a large gas bubble or slug through an inviscid liquid in a vertical tube, or between two flat plates. Experimental data show that the theory can be used to predict the rise of slugs in fluidised beds.

Circulating fluidised bed hydrodynamics
Powder Technology, 2000Abstract Analysis is given for flow regimes in the riser of a circulating fluidised bed (CFB) in the range of gas velocities (2–8 m/s) and particulate solids fluxes (15–90 kg/m2 s) appropriate for a CFB combustor. It is shown that the simplest version of the core-annulus model gives the correct magnitudes of slip velocity and average solids hold-up ...

Fluidised-Bed Granulation: A Chronology
Drug Development and Industrial Pharmacy, 1991AbstractThis paper is a chronological survey of published work in the field of pharmaceutical fluidised-bed granulation. It begins with early experiments in the 1960s and continues to include all relevant published work up to 1990. To aid the reader find published material for further in-depth reading a cross reference to published articles on a ...
