- Description
- Silo quaking refers to a phenomenon where material in a silo does not move smoothly, but rather in short sharp bursts known as quakes. The period between quakes can range from several minutes to tens of milliseconds, depending on the situation. The problem often presents in otherwise perfectly functioning silos with no other flow issues (flow from the outlet remains continuous). Sometimes the phenomenon can be viewed as a curious and benign oddity; however this is generally not the case. In an increasing number of systems, the associated dynamics generate significant structural loads that are of real concern. This study makes use of a scale model silo, which was mounted on load cells, to investigate the silo quaking mechanism for different material discharge rates. To compare with the experimental investigation, Discrete Element Modelling (DEM) was also used to investigate the quaking mechanism.
