“…In our previous work, [9], we discussed various techniques to account for nonsphericity of particles, such as polygon-shaped particles, multisphere composites, discrete function representation (DFR), and continuous function representation (CFR), where the last one proved to be superior in the scope of our work. In this context our previous work, [9], presented a novel frictional particle-wall and particleparticle collision model, applicable to any superellipsoidal particle collisions occurring in flows. The method proved to be efficient and robust even in the case where non-binary particle contacts occur, for example in filling processes, where a particle can be in contact with various other particles as well as the container wall.…”
