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…
Dimensional analysis for clogging of grains in two and three dimensions
Julián Montero, Ryan Kozlowski, Luis A. Pugnaloni
We conduct standard dimensional analysis (Vaschy--Buckingham -theorem) for the mean avalanche size when particles flow through, and clog at, a small orifice…
Flow rate from a vertical silo with a tilted orifice
Ryan Kozlowski, Luis A. Pugnaloni
The flow of dry granular materials from silos is of great practical interest in industry and of theoretical import for understanding multiphase dynamics. Recent studies have demons…
Intruder in a two-dimensional granular system: statics and dynamics of force networks in an experimental system experiencing stick-slip dynamics
R. Basak, R. Kozlowski, L. A. Pugnaloni +4
In quasi-two-dimensional experiments with photoelastic particles confined to an annular region, an intruder constrained to move in a circular path halfway between the annular walls…
Average outpouring velocity and flow rate of grains discharged from a tilted quasi-2D silo
Ryan Kozlowski, J. Carter Luketich, Elijah Oshatz +2
The flow of granular materials through constricted openings is important in many natural and industrial processes. These complex flows - featuring dense, dissipative flow in the bu…
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…
