T
he Discrete Element Method (DEM) has been widely
used as a mathematical tool for the study of flow
characteristics involving particulate solids. One distinct
advantage of this fast-developing technique is the ability
to compute trajectories of discrete particles. This provides
the opportunity to evaluate the interactions between
particle, fluid and boundary at the microscopic level using
local gas parameters and properties, which is difficult to
achieve using a continuum model. To date, most of these
applications focus on the flow behaviour. This paper
provides an overview of the application of DEM in gas-
solids flow systems and discusses further development
of this technique in the application of drying particulate
solids. Several sub-models, including momentum, energy
and mass transfer, have been evaluated to describe the
various transport phenomena. A numerical model has been
developed to calculate the heat transfer in a gas-solids
pneumatic transport line. This implementation has shown
advantages of this method over conventional continuum
approaches. Future application of this technique in drying
technology is possible but experimental validation is
crucial.
