Vila, A. (author), Pacha Sanjeevi, S.K. (author), Padding, J.T. (author), Pirker, Stefan (author)Fractures of particle assemblies happen frequently in dense gas-solid systems leading to a notable heterogeneity in the particle configuration, especially in case of cohesive powders and non-spherical particle interlocking. In this work, we investigate the influence of such heterogeneities on the hydrodynamic drag by studying the idealized...journal article 2019
