Experiments on the discharge of a silo with an inclined outlet are performed for three types of seeds. The angle of inclination is varied to cover the complete range from 0° to 90°. The theoretical description of the flow rate behavior as a function of the aperture angle is achieved taking into account the two types of regimes present in the problem: funnel and mass flow. The former is assumed to...
This is an experimental study of the discharge of seeds in a silo in a mass flow regime. It demonstrates how the flow parameters involved in Beverloo's equation (C and k) can be correlated with some of the shape parameters belonging to the seed grains. Results show that the concept of empty annulus introduced through the parameter k is dependent on the size and on the specific surface area. Besides,...
