Simulations of Granular Flow: Cracks in a Falling Sandpile
نویسنده
چکیده
We present numerical simulations of the fall of a two dimensional (2D) model granular material in a rectangular container and study the decompactionof this granular assembly consisting of non-cohesive particles. During the fall we observe the occurrence of cracks splitting the initial pile into pieces. Cracks preferentially occur in the lower part of the array, an eeect also observed experimentally. Using event driven simulations we vary dissipation and friction in order to understand the dynamics of the cracks. We classify the cracks quantitatively via an analysis using only on the coordinates of the particles.

Smoothing out sandpiles: rotational bulldozing of granular material
Predicting the dynamics of dense granular flow plays an important role in engineering and geophysical flow which involve the transport of granular materials such as for instance cereals, rocks or sand. In the past decade, most of the studies have focused on the flow of granular material on inclined surface due to the obvious applications in rock avalanches, landslides and pyroclastics flows [14...

The scaling properties of granular flows down an inclined plane are investigated in a model previously proposed to describe surface flows on a sandpile. Introducing a depth dependent friction, we are able to reproduce the results obtained experimentally by Pouliquen @Phys.

In this research, a two-dimensional mathematical model using turbulence model was developed in a rectangular channel with granular permeable bed. Finite volume method was used for numerical solution of governing equations. The equations considered are discretized using Hybrid difference scheme while applying SIMPLE algorithm to correct velocity components in the continuity equation. In the dev...
متن کاملAn existence result for the sandpile problem on flat tables with walls
We derive an existence result for solutions of a differential system which characterizes the equilibria of a particular model in granular matter theory, the so-called partially open table problem for growing sandpiles. Such result generalizes a recent theorem of [6] established for the totally open table problem. Here, due to the presence of walls at the boundary, the surface flow density at th...
متن کاملNumerical Simulation of Granular Column Collapses with Pressure-Dependent Viscoplastic Model using the Smoothed Particle Hydrodynamic Method
This paper presents a numerical analysis of granular column collapse phenomenon using a two-dimensional smoothed particle hydrodynamics model and a local constitutive law proposed by Jop et al. This constitutive law, which is based on the viscoplastic behaviour of dense granular material flows, is characterized by an apparent viscosity depending both on the local strain rate and the local press...
