Abstract: Cohesive granular materials such as wet sand, snow, and powders can flow like a viscous liquid. However, the elementary mechanisms of momentum transport in such athermal particulate fluids are elusive. As a result, existing models… read more here.

Abstract: We investigate numerically the impact process of a particle of diameter d and velocity V_{i} onto a cohesive granular packing made of similar particles via two-dimensional discrete element method simulations. The cohesion is ensured by… read more here.

DOI: 10.1103/physreve.97.042902
Abstract: Rheology of a dilute cohesive granular gas is theoretically and numerically studied. The flow curve between the shear viscosity and the shear rate is derived from the inelastic Boltzmann equation for particles having square-well potentials… read more here.

DOI: 10.7566/jpsj.87.094802
Abstract: Rheology of cohesive granular matter under the constant pressure condition is studied by means of molecular dynamics simulation. Depending on the shear rate, the pressure, and the cohesiveness, the system exhibits four distinctive phases: uniform… read more here.
