Descripción
Silos are containment structures widely used for storing granular materials. A good prediction of both the flow pattern developed during discharge and the pressures exerted by the stored material is required to ensure the functionality and integrity of the structure. Nowadays, the most suitable method to get knowledge about the flow pattern and the pressures is experimentally. However, this is not always feasible due to financial issues or requirements of the industrial activity. In the present study, Discrete Element (DE) analysis is used to simulate the flow pattern as well as wall pressure distributions in a small silo model filled with maize. The Hertz-Mindlin no-slip contact model with viscous damping and a frictional slider has been considered. The flow pattern was analysed by means of the vertical velocity profile at different levels of the silo during discharge. The wall pressure distributions where obtained by spatial-averaging and time-averaging the normal and tangential contact forces acting on each silo wall. In order to assess DE Method capabilities, these results are qualitatively compared against the expected behaviour proposed by analytical methods commonly used in practice.
