The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering
A new methodology of assessing large amounts of fluidized bed pressure fluctuation data with various signal analysis methods in combination with signal pre-treatment methods is presented. This approach can be used to find certain combinations that are selectively sensitive to certain physical effects in fluidized beds, such as agglomeration.

Positron Emission Particle Tracking (PEPT) has been used successfully to study pellet motion within the Wurster coater. PEPT experiments were undertaken to understand how the parameters of batch size and partition gap interact with each other; and to determine their effects on the particle cycle time and the components of the particle cycle time: the flight and annulus times and their respective distributions. This enabled the determination of optimum operating conditions for a given set of process conditions.

Positron Emission Particle Tracking (PEPT) is a versatile method for following the motion of a single radioactive tracer particle in a fluidised bed. However, there are many applications in which it would be useful to be able to follow the motion of two or more particles simultaneously in cooperative motion. The tracers are labelled with different intensities of radiation and located by converging sequentially on centres of activity. Two 600&#;m polyethylene particles have been followed in a 15 cm diameter bed and their contact events studied.

The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering
Large material, such as rocks, in a hydrotransport system of fine particles can damage pumps and equipment. A reliable, non-intrusive, and on-line acoustic method was developed for the detection of this large material. Analysis of signals recorded by microphones attached to the pipe wall allows for the reliable detection of rocks of different sizes and shapes, with no false positives.

The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering
The hydrodynamic patterns of gas flow associated with bubbles bursting at the surface of gas-fluidized beds have been investigated by means of planar laser induced fluorescence using acetone as diffusive gas tracer. The flow structures generated by the eruption of an isolated bubble have been characterized as a function of bed material size and of bubble injection level.

The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering
Pressure time data for binary mixtures of silica sand have been examined with particular reference to correlation between mean particle size, standard deviation and parameters obtained through attractor reconstruction techniques. The ratio of total variance to high speed variance is a particularly useful parameter for regime identification.

The 12th International Conference on Fluidization - New Horizons in Fluidization Engineering
In this paper, Electrical Capacitance Volume Tomography (ECVT) is used to study a gas-solid fluidized bed system of .1 m ID. The interior flow structures (including the dynamic bed expansion, bubble/void breakage and particle movement) and the charge distribution in a gas-solid fluidized bed are illustrated based on the 3D images obtained from the ECVT.
