  • A differential equation for the flow rate during silo discharge Beyond the Beverloo rule 

    Madrid, Marcos A.; Darias, José Ramón; Pugnaloni, Luis (EPJ Web of Conferences, 2017)
    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 contrast with the traditional derivations based ...

  • Determination of the angle of repose and coefficient of rolling friction for wood pellets 

    Madrid, Marcos A.; Fuentes., José María; Ayuga, Francisco; Gallego Vazquez, Eutiquio; 0000-0002-0891-0063; 0000-0002-1320-4534; 0000-0002-8904-9534 (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 

    Darias, José Ramón; Madrid, Marcos A.; Pugnaloni, Luis (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 

    Gago, Paula; Madrid, Marcos A.; Boettcher, Stefan; Blumenfeld, Raphael; King, Peter (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 ...

  • On the use of magnetic particles to enhance the flow of vibrated grains through narrow apertures 

    Carlevaro, Manuel; Kuperman, Marcelo N.; Bouzat, Sebastián; Pugnaloni, Luis; Madrid, Marcos A. (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 

    Madrid, Marcos A.; Irastorza, Ramiro; Meyra, Ariel G.; Carlevaro, Manuel (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 ...
