| Popis: | The mixing of a packed bulk material consisting of non-cohesive mechanically identical particles during shearing is modelled mathematically with the aid of a diffusion equation. In this paper, an equation relating the diffusion coefficient proportionally to the shear rate is derived. This prediction was verified experimentally by shearing experiments using a Couette apparatus. The model bulk consisted of vertically packed cylindrical metal rods, marked by colouring. |
