Analysis of the velocity field of granular hopper flow
F. G. R. Magalhães, A. P. F. Atman, J. G. Moreira +1
We report the analysis of radial characteristics of the flow of granular material through a conical hopper. The discharge is simulated for various orifice sizes and hopper opening…
Jamming transition in a two-dimensional open granular pile with rolling resistance
Caio F. M. Magalhães, Allbens P. F. Atman, Gaël Combe +1
We present a molecular dynamics study of the jamming/unjamming transition in two-dimensional granular piles with open boundaries. The grains are modeled by viscoelastic forces, Cou…
Transitions in a Probabilistic Interface Growth Model
S G Alves, J G Moreira
We study a generalization of the Wolf-Villain (WV) interface growth model based on a probabilistic growth rule. In the WV model, particles are randomly deposited onto a substrate a…
New method to study stochastic growth equations: a cellular automata perspective
T. G. Mattos, J. G. Moreira, A. P. F. Atman
We introduce a new method based on cellular automata dynamics to study stochastic growth equations. The method defines an interface growth process which depends on height differenc…
Morphological transition between diffusion-limited and ballistic aggregation growth patterns
S. C. Ferreira, S. G. Alves, A. Faissal Brito +1
In this work, the transition between diffusion-limited and ballistic aggregation models was revisited using a model in which biased random walks simulate the particle trajectories.…
Growth model with restricted surface relaxation
T. J. da Silva, J. G. Moreira
We simulate a growth model with restricted surface relaxation process in d=1 and d=2, where d is the dimensionality of a flat substrate. In this model, each particle can relax on t…
