Experimental Investigation of Leakage Flow Rate and Fluidisation beneath Polyethylene Pipes in Non-Uniform Soils [PDF]
Water (Switzerland)Soil fluidisation around buried pipes is one of the water leakage effects that has a direct influence on the ultimate failure of pipelines. In this research, using a laboratory model, the fluidisation caused by water leakage from three cracks with three ...

Powder Technology, 1990
Abstract A method to calculate the particle size distribution of irregularly shaped particles from measurement of the pressure drop obtained when a liquid is initially passed through a fixed bed of powder prior to subsequent fluidisation, has been developed from the measurement of pressure drop as a function of volumetric liquid flux during ...

Abstract The open channel flow behaviour of fluidised solids is compared with the results from small-scale tests using a modified Brookfield viscometer. The fluidised solids displayed a similar range of non-Newtonian flow properties in both series of tests but the small-scale tests cannot yet be directly applied to predict the deeper, full-scale bed ...

Abstract Induced particle circulation was studied in a 0.3 m diam. air fluidised bed of sand with central draught tubes of 0.2 m and 0.15 m diam. and 0.6 m and 1.2 m in length. A “two-dimensional” bed, 0.3 m in width, of similar cross-section, was also used to study catalyst particle circulation.

Proceedings of the Institution of Electrical Engineers, 1969
Use of electroheated fluidised beds is a fast-growing branch of electroheating, but this growth has been hampered because the models available hitherto were incomplete, in that they ignored flow and mode dependence and were unnecessarily complicated for the engineer concerned with practical industrial processes.

La fluidisation consiste a faire passer une phase fluide (tres souvent un gaz) a travers un lit de particules, supportees par une grille, pour les mettre en suspension. Le terme fluidisation vient du fait que la suspension gaz/solide est amenee dans un etat semblable a celui des fluides.

Hydrodynamics of liquid fluidisation
Chemical Engineering Science, 1995Abstract Theoretical and empirical approaches to the fluid dynamic description of liquid fluidised beds are reviewed, together with the relevant experimental evidence. Attention has been focused, in the main, on steady- and unsteady-state phenomena relating to monocomponent fluidised beds, with one section devoted to binary-solid systems, the ...

The fluidised combustion of coal
Symposium (International) on Combustion, 1977Fundamental and engineering aspects of fluidised combustion are reviewed. The main areas discussed include: u - the application of the two phase theory of fluidisation to the combustion of coal, - the relevance of available information on the kinetics of volatile evolution, volatile combustion and of the carbon-oxygen and carbon-carbon dioxide ...

FLUIDISATION OF SOLID PARTICLES
1989A fluidised bed is formed when a gas or liquid passes up through a bed of particles at a rate such that the pressure drop is sufficient to support the weight of the particles. The bed of fluidised particles has many of the properties of an ordinary liquid.
