Abstract:
Discrete Element Method (DEM) simulations are a promising approach to accurately predict agglomeration and deposition ofmicron-sized adhesive particles. However, themechanistic models in DEM combined with high particle stiffness for most common materials require time step sizes in the order of nanoseconds,which makes DEM simulations impractical for more complex applications. In this study, analytically derived guidelines on how to reduce computational time by using a reduced particle stiffn...     »
