Solids flow patterns in large-scale circulating fluidised bed boilers: Experimental evaluation under fluid-dynamically down-scaled conditions

Fluidised Bed Microencapsulation of Ascorbic Acid: Effectiveness of Protection under Simulated Tropical Storage Conditions

This study investigates the use of microencapsulation by fluidised bed coating for the protection of ascorbic acid during long-term storage under simulated tropical conditions. Microencapsulation materials, loading levels, fluidised bed processing conditions and the results of storage trials were evaluated. Cellets® 350 is a suitable base material, whereas sugar spheres are not suitable due to ...

Liquid transportation fuels via large-scale fluidised-bed gasification of lignocellulosic biomass

With the objective of gaining a better understanding of the system design tradeoffs and economics that pertain to biomass-to-liquids processes, 20 individual BTL plant designs were evaluated based on their technical and economic performance. The investigation was focused on gasification-based processes that enable the conversion of biomass to methanol, dimethyl ether, Fischer-Tropsch liquids or...

Fluidised bed drying of soybeans.

The 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. From a quality point of view, fluidised bed drying was found to reduce the level of ure...

Rock Stability under Different Fluid Flow Conditions

Very-large-scale motions in rough-bed open-channel flow

Long-duration particle image velocimetry measurements in rough-bed open-channel flows (OCFs) reveal that the pre-multiplied spectra of the streamwise velocity have a bimodal distribution due to the presence of largeand very-large-scale motions (LSMs and VLSMs, respectively). The existence of VLSMs in boundary layers, pipes and closed channels has been acknowledged for some time, but strong supp...
