Heat management problems often prevail in reactors when highly exothermic chemical reactions occur. In these situations, fluidised bed are preferred due to their excellent heat transfer capabilities. However, the design, scale-up and operation of is still challenging complex hydrodynamics. To gain a better understanding on transport reactors, degree temperature non-uniformity for several fluidi...

Artificial tree hollows (e.g., nest-boxes) are commonly deployed to mitigate the loss of mature trees within human-disturbed landscapes. Their effectiveness as a habitat resource, and thus conservation management tool, is strongly influenced by suitability internal microclimate conditions. In south-eastern Australia, spout nesting resource used diverse community vertebrate species. We tested no...

A theoretical framework has been developed describing nonequilibrium formation and maintenance of mixed-phase clouds. The necessary and sufficient conditions required to activate liquid water within a preexisting ice cloud, and thus convert it to mixed phase, are considered for three scenarios: (i) uniform ascent, (ii) harmonic vertical oscillations, and (iii) turbulent fluctuations. The genera...

The hydrodynamic behaviour of the spouted bed has been studied by considering the different system parameters (viz. static bed height, spout diameter, particle size, gas velocity and particle density). Experiments were carried out using a Perspex column of 4 inch diameter. Attempts have been taken to develop correlations for the bed expansion / fluctuation ratios by varying different system par...

There are two types of nodes, called “spouts” and “bolts”. A spout is a source of streams (sequences of tuples). In case of the KBA track, a spout would read document data from the provided KBA corpus and emit them as a stream. A bolt receives any number of input streams, does some processing, and may emit new streams. For the KBA track, bolts would determine whether inbound documents from the ...
