Based on the physical knowledge, a theoretical model of highconcentrated granulated medium dynamics is developed for the case of a gravitational and confined flow. In the suggested model, rheological properties of the granular medium and slipping effects of particles on solid surfaces are taken into account. The resulting velocity profile based on the model is compared with experimental data for the case of flow of granular material around a quadratic obstacle in a vertical channel.
Keywords: rheology, stress tensor, viscosity, velocity, granular medium, slipping condition, strain velocity deformation, flow function
