Discrete Element Method

Introduction

Discrete Element Method (DEM) is a particle-based method which involves tracking the position, velocity and spin of all the individual particles and their neighbouring boundary objects, as well as detecting and modelling all collisions between particles and with the objects.

Type of phenomena treated

DEM is ideal for modelling dry or moist granular material or powder for which particle collisions dominate the flow behaviour. DEM can be used to simulate a wide range of phenomena, including:

    • mixing, segregation
    • breakage, attrition
    • surface wear
    • bridging, funnel flows
    • agglomeration, granulation
    • transport
    • ...

What you can get from DEM simulations

A large number of physical properties associated with granular processes can be determined, including:

  • flow characteristics
  • power draw
  • surface forces and wear rates
  • mixing and segregation rates
  • particle agglomeration and breakage rates
  • particle energy spectra
  • collisional energy losses
  • ...

DEM expertise

The know-how gained by Granulair Technologies has been applied to a wide range of industrial processes. An advanced DEM software package has been developed and continual enhancements are being made through the incorporation of additional advanced physical models.
