(150b) Toward Simulation-Based Design of Particle Handling Processes
Specifically, this presentation will focus on DEM modeling of complex particulate flows for non-spherical particles which are described via linked and overlapping spheres. In addition, both rigid and flexible non-spherical particles, including particle breakage, will be discussed. Finally, we consider the effect of cohesion of non-spherical particles via liquid bridging. The particle models are validated via experiments - shear cells testing, angle of repose testing, hopper discharge, particle packing, and particle breakage due to compaction and flow in a FT4 rheometer. These aspects of particle flow (asphericity, flexibility, breakage and cohesion) are of great importance in many practical applications and, hence, are the subjects of research at the forefront of current particle modeling efforts.
