Two-phase viscous modeling of compaction of granular materials
An inviscid model for deflagration-to-detonation transition in granular energetic materials is extended by addition of explicit intraphase momenta and energy diffusion so as to ~1! enable the use of a straightforward numerical scheme, ~2! avoid prediction of structures with smaller length scales than the component grains, and ~3! have a model prepared to describe long time scale transients that...
متن کاملCompaction of anisotropic granular materials: experiments and simulations.
We present both experimental and numerical investigations of compaction in granular materials composed of rods. As a function of the particles size and with respect to the container diameter, we have observed large variations of the asymptotic packing volume fraction. The relevant parameter is the ratio between the rod length l and the tube diameter D . Even the compaction dynamics remains unch...
متن کاملCompaction of granular materials: experiments and contact dynamics simulations
We present an original experimental study of the slow compaction dynamics for twodimensional isotropic granular systems. Compaction dynamics is measured at three different scales : the macroscopic scale through the normalized packing fraction ρ̃, the mesoscopic scale through the normalized fraction φ̃ of domains ideally ordered in the system, and the microscopic scale through the grain mobility μ...

متن کاملExperimental study of the compaction dynamics for two-dimensional anisotropic granular materials.
We present an experimental study of the compaction dynamics for two-dimensional anisotropic granular systems. The compaction dynamics of rods is measured at three different scales: (i) the macroscopic scale through the packing fraction rho, (ii) the mesoscopic scale through both fractions of aligned grains phi(a) and ideally ordered grains phi(io), and (iii) the microscopic scale through both r...
