CFD-DEM simulation of spray-coating in fluidized bed

This is a simulation of spray-coating in a fluidized bed, often used to add active or inactive ingredients or to coat particles.

This is a simulation of spray-coating in a fluidized bed, often used to add active or inactive ingredients or to coat particles. The fluidized bed is simulation using CFD-DEM, additionally the spray is fully resolved in a Lagrangian way (subject to fluid forces). Particles then capture the spray and get wetted. Optionally, particles can transfer the liquid content from one to another, and the particle-particle interaction laws can be extended by e.g. liquid bridge forces.
