Silo Discharge - Funnel and Rat Holing

#shorts #silosystem #demsimulation #engineering
Silos store and discharge bulk materials, with particle outflow depending on the bottom angle. Steep angles result in "mass flow," where particles move uniformly downward for complete discharge. Shallow angles cause "funnel flow," where particles concentrate in the center, leaving material near the walls. Sometimes, a tap is needed to activate discharge due to "rat holing."
Externally, steep angles show mass flow, while funnel flow concentrates particles in the middle. Cross-sections reveal even velocities for mass flow and the creation of a funnel shape for funnel flow.
Mass flow follows a "first in - first out" order, while funnel flow mixes layers. A video shows the visible funnel shape in a "funnel flow silo."
Understanding these flow behaviors is vital for optimizing silo design and material handling.
