Abstract

Wet granular materials in steady-state in a quasi-static flow have been studied with discrete particle simulations. The total torque is an experimentally accessible macroscopic quantity that can be used to investigate the shear strength, bulk cohesion and other properties of the materials. We report in this paper how the macroscopic bulk cohesion and torque required to rotate the system change with the liquid content. Consequently, micro-macro correlations are obtained for the macro properties as a function of the microscopic liquid bridge volume which is one factor dominating the contact force.
