Descripción
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.
