On the use of magnetic particles to enhance the flow of vibrated grains through narrow apertures
(2021-06-28)
The ow 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 always part of the design of machinery for ...
Self-assembly of self-propelled magnetic grains
(2021)
In this work, we study bidisperse mixtures of self-propelled magnetic particles of di erent shapes
via discrete element method simulations. We show how these particles self-assemble into clusters and how these clusters ...
Determination of the angle of repose and coefficient of rolling friction for wood pellets
(2022-02-08)
The determination of the angle of repose for granular materials is indispensable for their handling and the design of containers and technological processing equipment. On the other hand, computational simulations have ...
Differential equation for the flow rate of discharging silos based on energy balance
(2020-05)
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 of dimensional analysis
and experimental ...
Effect of bevelled silo outlet in the flow rate during discharge
(2023-07-29)
We investigate the effect of a bevelled (or slanted) outlet on the discharge rate of mono-sized spheres from a quasi-two-dimensional silo, using the discrete element method. In contrast to hopper discharges, where the ...
