With recent advancements in numerical simulation technology, it is now possible to effectively simulate and understand the behavior of bulk material handling and granular flows.
In STAR-CCM+, the Discrete Element Method (DEM) is used to simulate particle flow for these applications.
DEM can be used to simulate the motion of a large number of interacting discrete particles, such as the granular flow of sand, food particles, metal powders, capsules and slurries. DEM tracks the interaction between every particle in a numerically efficient manner, modeling contact forces and energy transfer due to collision and conductive and radiative heat transfer between particles.
STAR-CCM+ is the first commercial engineering simulation tool to include a DEM capability that is fully coupled with numerical flow simulation in a single software environment.
The potential industrial applications of DEM include:
