Modeling of a Cohesive, Caking Powder in DEM Simulations — •Alexander Weuster and Dietrich E. Wolf — Uni DuE and CeNIDE, Duisburg, Germany

As the capacity of modern computers increases, it has become feasible to do simulations of bulk solids with particle numbers close to those in real experiments. Capturing every detail, however, remains a challenge, especially when dealing with non-spherical, cohesive particles and a large particle size distribution. Using the the example of µm-sized potassium chloride (KCl), we will present an approach to model a cohesive, caking powder in DEM-Simulations. By calibration of an idealized ensemble of spheres, we are able to reproduce the macroscopic flow properties of KCl observed in experiments.
