Granular materials play a crucial role in various industries, sparking a growing interest in the development of virtual prototypes to replicate industrial scenarios. However, these materials show complex behaviours across different time and length scales that challenge traditional simulation methods. While the discrete particle method (DPM) offers a promising solution by accurately capturing key physics, it solves Newton?s laws per particle and is computationally prohibitive for large-scale industrial applications. This talk gives a brief overview over my thesis titled "Virtual prototyping of wet granulation processes", and discusses the quadrature-based moment methods which were used to model a twin-screw wet granulation process in more detail. Furthermore, it will close with an introduction to model order reduction of discrete particle systems - the ongoing effort of a collaboration between the university of Münster and University of Twente in Enschede.
