Natural and industrial granular flows often consist of several particle sizes, approximately forming a continuous particle size distribution (PSD). Continuous PSDs are ubiquitous, though existing kinetic-theory-based, hydrodynamic models for rapid granular flows are limited to a discrete number of species, many restricted to only two particle species. The objective of this effort is threefold: (i) to determine the importance of finite-volume (non-dilute) effects of solid particles in binary mixtures, (ii) to determine the minimum number of discrete particle species needed to accurately approximate a continuous PSD, and (iii) to validate discrete approximations of continuous PSDs applied to a kinetic-theory-based model via comparison with MD simulations.
