Tutorials

Each solver of CFDEM®coupling comes with at least one tutorial example, showing its functionality and correct usage. Provided that the installation is correct, the tutorials can be run via the included Autorun.sh script, see Run a simulation for more details.

Validation cases

CFDEM®coupling is being validated constantly and extensively and many results can be found in in peer-reviewed publications. Specific cases which are validated against analytical and, especially, experimental results are highlighted in this section:

Prismatic fluidized bed	Fluidization in a spout bed	Bubble Column	Ergun test vs. analytic
Particle settling (resolved)	Particle settling (unresolved)	Particle settling vs. analytic	Settling of two spheres

Use cases

Mill with liquid-gas surface

Spray granulation

Erosion around an obstacle

Particle separation in flow

• Thermal runaway in Li-ion cells

Setups for different particle shapes

Simulation setups can easily be expanced to the different particle shapes available in CFDEM®coupling (i.e, spheres, multispheres, superquadrics and convex). The following setup gives a concise example in the required steps and options:

• Spout bed for different particle shapes
