PROJEKTIRANJE SILOSA S ASPEKTA NAČINA PROTOKA MATERIJALA PRI PRAŽNJENJU

This article deals with the material flow problems of a cylindrical conical steel silos during discharge. Since the silos discharge process belongs to one of the most critical load cases, it is necessary to be accounted for during design. During the silos discharge the several modes of material flow can occur. Due to fact that each of the flow modes result in significantly different pressures on the silos walls, from the safety and economical aspect, it is required to have reliable assessment of the discharge process. Depending on the silos purpose and stored material properties it is necessary to design with aim to achieve the desired discharging mode. In conclusion, the present work, through the numerical analysis, gave insights into how the small variations in the silos structural geometry can cause different discharging modes.
