Arching during the segregation of two-dimensional tapped granular systems: Mixtures versus intruders

We present numerical simulations of binary mixtures of granular disks subjected to tapping. We consider the size segregation process in terms of the arches formed by small and big particles. Although arching has been proposed as one of the chief mechanisms that determines size segregation in non-con...
