IMPACT OF GRANULAR FLOW DYNAMICS ON THE DESIGN AND MODELLING OF THE BUNKERS

Silos and bunkers are widely used in the storage, storage and distribution of granular materials, of particular importance in the management of handling, transport and conditioning operations. The distribution of seeds at the filling and emptying stage of the bunker examines the main loading and unloading hypotheses leading to different limit states for its structure. This paper will present the results of causes such as the maximum pressure perpendicular to the vertical wall of the silo, the maximum stretching effort due to friction with the vertical wall, the vertical pressure on the basis of it and the maximum load on the bunker funnel, resulting in the implementation of new design and modeling solutions. At the same time, the dynamics of the granular flow in the bunkers, including flow regimes, design and optimal shapes, will be described to avoid the loss of energy generated by the collision of macroscopic particles inside it
