چکیده
In this paper we report experimental results on the granular temperature and velocity profile of glass beads in steady-state flow inside a flat-bottomed silo. We found that dynamics system during discharge is stable mesoscopic scale. particular, ordered directional movement particles can occur near orifice. addition, correlation between distribution vector field opposite radial axial directions. According to kinetic model, main cause for reversal spatial intensity particle diffusion decrease with silo height. This highlights surprising unrecognized role motion plays energy dissipation hopper flow.

Velocity profile of granular flows inside silos and hoppers
We measure the flow of granular materials inside a quasi-two-dimensional silo as it drains and compare the data with some existing models. The particles inside the silo are imaged and tracked with unprecedented resolution in both space and time to obtain their velocity and diffusion properties. The data obtained by varying the orifice width and the hopper angle allow us to thoroughly test model...
متن کاملSimulation 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 ...

متن کاملSEISMIC BEHAVIOR OF SILOS WITH DIFFERENT HEIGHT TO DIAMETER RATIOS CONSIDERING GRANULAR MATERIAL-STRUCTURE INTERACTION
Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...
متن کاملA Study of the Wave Propagation Velocity in Granular Soils Using Discrete Element Method (DEM)
In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...
