“…It is worth to mention that our simulation reproduces qualitatively our experimental state diagram already presented in [6]. Finally, when the injection point oscillates, the striae almost disappear and the mixture of grains is improved, emulating the experimental results.…”

“…We have studied the phenomenon of segregation and mixture during the construction of granular piles [5][6]. The experimental device allows us building piles of, at most, two different species of grains inside a quasi bi-dimensional transparent acrylic plexiglass cell.…”

“…4 we show a pile corresponding to this case. The different final structural configurations of the piles obtained with the simulations were characterized through the definition of two indices of segregation I H and I ⊥ as in [6].…”

“…For very small values of δ (∼7.5x10 -3 ), this method yields a realistic simultaneous deposition of grains with zero restitution coefficient. Given the short extension of the present paper, we encourage the reader to see the details of this method in [6,7].…”

Abstract. We report a numerical study of the problem of flow segregation in quasi bidimensional piles built up by pouring a mix of grains of two different sizes from a constant height. To simulate the pile formation, we employ a pseudo-dynamics method (PSDM). The concentration of small and big grains is varied. We also try with different size ratios between the beads. The segregation patterns arising after the pile is finished are studied by analyzing the spatial distribution of the grains. Two different segregation indices are defined and evaluated over the piles. The conditions under which the different segregation patterns show up are discussed. A comparison of all the results obtained with our own experimental results, is performed. The patterns and the different conditions for the setting up of segregation are discussed. The advantages and limitations of the simulation model are discussed.

“…Material properties is an important factor affecting the segregation of granular materials [3,4,5]. Among them, the size and density of particles have been widely investigated [6][7][8][9][10][11][12]. Liao et al [13] studied the granule segregation in a rotating drum.…”
