Simulation of Gravity Flow of Granular Materials in Silos
The problem of determining the steady state flow of granular materials in silos under the action of gravity is considered. In the case of a Mohr-Coulomb material, the stress equations correspond to a system of hyperbolic conservation laws with source terms and nonlinear boundary conditions. A higher order Discontinuous Galerkin method is proposed and implemented for the numerical resolution of ...

15 صفحه اولPhysically Accurate Granular flow Simulation
Discrete element simulation models large collections of solid bodies as individual bodies, rather than attempt to approximate the system via continuum models and partial differential equations. However, standard models for rigid bodies are inadequate as they do not incorporate elastic vibrations. An alternative to both rigid body models and finite element simulations is presented that is highly...
متن کاملApplication of an Uncoupled ALE-formulation to Confined Granular Flow in Silos
The paper describes results of FE-simulations of confined granular flow in silos with and without inserts. The numerical analysis was performed with the help of an uncoupled Arbitrary Lagrangian-Eulerian (ALE) approach. The behaviour of the granular material was described with a non-local hypoplastic model. The FEresults of silo flow were compared with experiments in a large-scale silo. Both th...
متن کاملDiscrete Particle Simulation of Granular Flow
Granular materials, which can be either wet or dry and range from nanometers to centimetres in size, are widely encountered in industries and in nature. As with solids, they can withstand deformation and form heaps; as with liquids, they can flow; as with gases, they exhibit compressibility. These features give rise to another state of matter that is poorly understood (Ennis et al., 1994; Jaege...
