Forced silo discharge: Simulation and theory
Luis. A. Pugnaloni, Marcos A. Madrid, J. R. Darias
We study, through discrete element simulations, the discharge of granular materials through a circular orifice on the base of a cylindrical silo forced by a surcharge. At the begin…
On the use of magnetic particles to enhance the flow of vibrated grains through narrow apertures
C. Manuel Carlevaro, Marcelo N Kuperman, Sebastián Bouzat +2
The flow of grains through narrow apertures posses an extraordinary challenge: clogging. Strategies to alleviate the effect of clogging, such as the use of external vibration, are…
Enhancement of the flow of vibrated grains through narrow apertures by addition of small particles
Marcos A. Madrid, C. Manuel Carlevaro, Luis A. Pugnaloni +2
We analyze the flow and clogging of circular grains passing through a small aperture under vibration in two dimensions. Via Discrete Element Method simulations, we show that when g…
Differential equation for the flow rate of discharging silos based on energy balance
J. R. Darias, Marcos A. Madrid, Luis A. Pugnaloni
Since the early work of Hagen in 1852 and Beverloo et al. in 1961, the flow rate of granular material discharging through a circular orifice from a silo has been described by means…
Velocity profiles in forced silo discharges
Marcos A. Madrid, Luis A. Pugnaloni
When a granular material is freely discharged from a silo through an orifice at its base, the flow rate remains constant throughout the discharge. However, it has been recently sho…
Forced flow of granular media: Breakdown of the Beverloo scaling
Marcos A. Madrid, J. R. Darias, Luis A. Pugnaloni
The Beverloo scaling for the gravity flow of granular materials through orifices has two distinct universal features. On the one hand, the flow rate is independent of the height of…
A differential equation for the flow rate during silo discharge: Beyond the Beverloo rule
Marcos A. Madrid, José R. Darias, Luis A. Pugnaloni
We present a differential equation for the flow rate of granular materials during the discharge of a silo. This is based in the energy balance of the variable mass system in contra…
