Particle Scale Study of Particulate Systems

Abstract

Discrete particle simulation has been extensively used in the laboratory of particulate and multiphase processing at the University of New South Wales (UNSW) to study the fundamentals of particulate matter at a particle scale. This paper briefly reviews the work in the laboratory, which covers the development of simulation techniques and their application to the study of typical static or dynamic particulate systems including particle packing, sandpiling, particle flow in bladed mixer, rotating drum and hopper, gas-solid flow in packed and fluidized beds. Emphasis is given to the validity analysis of the simulation method and the usefulness of the resulting particle scale information in elucidating the underlying physics.
