Pneumatic conveying systems are widely used for the transport of
granular solids in various industries. It is well recognized that a
common and sometimes hazardous phenomenon associated with
this type of transport system is the attrition and electrostatic charge
generation via solid-wall or solid-solid interactions. The present
project aims to correlate electrostatics, granular attrition, and
granular dynamics properties for characterization of such systems.
Specific tasks include: (1) studying electrostatic effects on solid
flow behaviour; (2) investigating granular attrition due to rotary
valve in pneumatic conveying systems; (3) characterizing charge
capacity of single particle with various particle size and shape; (4)
establishing the fundamental relationships between the
above-mentioned components and flow behaviours observed.
