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 ...

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.

Gas distributor in fluidised beds
Powder Technology, 1978Abstract Satisfactory performance of fluidised bed reactors in terms of bed characteristics, chemical conversion and power requirement for pumping the fluidising medium is influenced by the design features of gas distributors. In industrial practice multi-orifice types of distributors are frequently used.

THE FLUIDISED BED COATING PROCESS
Anti-Corrosion Methods and Materials, 1963During recent years the use of the fluidised‐bed method of applying plastics coatings to metals has increased considerably. The plastic is in the form of a powder kept in a suspended or ‘fluidised’ state by injecting air into the bed of powder. After cleaning, the article is preheated to a temperature above the melting point of the particular powder ...

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.

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.

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.

The Kinetics of Segregation in Fluidised Beds
2000It is well known that particles in the fluidised state will segregate if their sizes or densities are sufficiently different. However, little research has been carried on the kinetics of this separation, nor on the separation of particles below 300μm; in addition, the effect of the distributor design on a segregating system has not been investigated ...

Since the introduction of the ‘wirbelschicht’ in Germany in the 1920s, fluidised beds have played a transformative role in chemical engineering. However, as demands for efficiency, control, and sustainability have grown, so too has the need to further intensify fluidisation processes beyond the earlier conventional designs.

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.
