N2 - First rheological investigation results of weakly wet granular media are presented. The materials have been examined experimentally and numerically in well- defined shear configurations in steady state, in the intermediate flow regime. For the experiments, a Searl-type ring shear cell with rotating inner cylinder and fixed outer cylinder is used. In the numerical particle simulation approach, a split-bottom shear cell is used. Relevant local continuum flow fields (e.g. velocity, stress, shear rates) are determined by micro-macro transition from the simulations data. After the simulations are validated by experiments, e.g. by comparison with the experimentally accessible quantities like shear-torque at the inner wheel, they can give a deeper insight into the microscopic kinematics. The granular media have considerably more “wet contacts” in the shear zone, as for example the location-plot of purely wet bridges, without mechanical contacts suggests. Finally, critical state flow rules concerning the viscosity of wet granular materials are discussed.
