Abstract:

The rheology of dense granular assemblies is studied using large-scale molecular dynamics simulations for the case of gravity driven flows in an inclined plane geometry, i.e. chute flow. Over a wide range of parameter space, a steady state flow regime exists in which the energy input from gravity balances that dissipated from friction and inelastic collisions. The corresponding phase behaviour is discussed. Within the steady state regime the flow velocity depth-profile is seen to depend on how close the system is to jamming and matches several experimental studies. Static granular packings are also discussed.
