In this session we will discuss Simcenter STAR-CCM+ capabilities to model Chemical Vapor Deposition on particles in a Fluidized bed using DEM and PRM (Particle Reaction Model) What you will learn in this session: 1) How DEM and PRM two-way coupling works in STAR-CCM+ 2) How to use Particle Reaction Model for coating applications in STAR-CCM+ 3) How to choose your DEM time-step 4) Tips to prevent solution divergence when running such complex DEM physics
