Integrating Dynamic Scale Modelling with DEM to Enhanced Transfer Chute Design
DEM and DEM-Coupled simulations are widely used to study and predict the behavior of powders and granular materials in industrial processes. DEM parameters should reflect particle-level properties, but accounting for each particle's shape, size, and surface is often impractical on an industrial scale. Instead, a coarse-grained material representation is used, requiring calibration to match macroscopic behavior. DEM parameters derived from laboratory or physical modeling will vary from theoretical values, making accurate calibration essential for reliable analysis. This presentation discusses findings and intricacies of applying physical scale modelling, material characteristics and DEM to transfer chute design.
