Time scales and rheology of visco-cohesive granular flows

In the presence of viscous and cohesive interactions between particles, a granular flow is governed by several characteristic time stress scales that determine its rheological properties (shear stress, packing fraction, effective viscosities). this paper, we revisit extend scaling arguments used previously for dry cohesionless flows suspensions. We show rheology can be in principle described single dimensionless control parameter includes all times. also briefly present simulation results 2D sheared suspensions 3D wet where friction coefficient fraction are consistently as functions unique parameter.
