Emergence and Solidification-Fluidisation
2021The Artificial Intelligence (AI) paradigm is based on the mirroring of human Natural Intelligence (NI) into a technical machine concept, with the aim of maximising computability in the von Neumann sequential manner. The goal of this article is to give some key prospects of general and actually foreseen global parameters for some AI-NI properties ...

The expansion of gas-fluidised beds in bubbling fluidisation
Chemical Engineering Science, 1997The expansion of gas-fluidised beds has been examined in the range of Archimedes number from 100 to 105 using five grades of glass ballotini and two grades of lead shot of narrow size distribution, and Diakon particles of wide size distribution. A porous plastic distributor plate was used in beds of diameters 89 and 290 mm.

Characteristics of fluidisation behaviour in a pressurised bubbling fluidised bed
The Canadian Journal of Chemical Engineering, 2012AbstractThe experiments were carried out in a bench‐scale fluidised bed of 90 mm in diameter to determine the influence of pressure on fluidisation characteristics of Geldart A and B particles over the range of pressure 0.1–4.5 MPa. For Geldart B particles, the results indicate that minimum fluidisation velocity (umf) was found to decrease with ...

Hydrodynamic scaling relationships for fluidisation
Applied Scientific Research, 1991Summary: The scaling rules for fluidization are obtained from a closed formulation of the equations of change that incorporates a fluid dynamic mechanism for particle pressure. The rules are compatible with previous ones, based on formulations that omit particle pressure, thereby extending their validity to gas fluidized fine powders and liquid systems

The process of fluidisation involves blowing warm air through small solid microspheres thus creating a liquid, without wetness. The warmth provides some important properties including reducing the metabolic rate in thermal injury which has a beneficial effect on mortality, modifying catabolism after surgery, providing gradual vasodilation in shock and ...

Fluidised bed drying of soybeans
Journal of Stored Products Research, 2001The fluidised bed drying characteristics of soybeans at high temperatures (110-140 degrees C) and moisture contents, 31-49% dry basis, were modelled using drying equations from the literature. Air speeds of 2.4-4.1 m/s and bed depths from 10 to 15 cm were used. The minimum fluidised bed velocity was 1.9 m/s.

Quality of Fluidisation for the Drying of Forestry Biomass Particles in a Fluidised Bed
Biosystems Engineering, 2006The objective of this work is to analyse three methods of forest biomass particles fluidisation, applied to the drying of solids. The techniques to promote fluidisation are: vibro-fluidised bed, mechanically agitated fluidised bed and fluidised bed with inert solids.

Dynamic modelling of fluidisation in gas-solid bubbling fluidised beds
Powder Technology, 2017Abstract Formation of fluidised bubbles in a fluidised bed has significant impact on the design and scale-up of the bubbling fluidised bed. To fully understand bubble motions in the fluidised bed, fluidised bubble dynamics in a gas-solid fluidised bed is investigated using CFD-DEM numerical simulation.

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 ...

Intelligent fitting of minimum spout‐fluidised velocity in spout‐fluidised bed
The Canadian Journal of Chemical Engineering, 2010AbstractThe experiments were carried on to study the minimum spout‐fluidised velocity in the spout‐fluidised bed. It was found that the minimum spout‐fluidised velocity increased with the rise of static bed height, spout nozzle diameter, particle density, particle diameter, fluidised gas velocity but decreased with the rise of carrier gas density ...
