The Importance of Fluid-Particle Interactions for Fluidized Systems Modeling

This presentation discusses the importance of capturing fluid-particle interactions in computational models of fluidized systems. While direct particle to particle interactions are certainly important and computational modeling in general would benefit from an improved understanding of these interactions, a primary interaction mechanism influencing fluidized systems is the interaction between the particles and fluid. This presentation discusses the importance of fluid-particle coupling via aerodynamic/hydrodynamic drag, how particle-fluid interactions impact particle to particle interactions, validation of modeling for fluidized industrial systems, the effect of particle size distribution including fines, limitations of existing models, and how current research trends can enable expanded industrial application of modeling technology impacting efficient and rapid commercialization and scale-up of new and improved particle technologies.
