Three-dimensional shear in granular flow.
The evolution of granular shear flow is investigated as a function of height in a split-bottom Couette cell. Using particle tracking, magnetic-resonance imaging, and large-scale simulations, we find a transition in the nature of the shear as a characteristic height H* is exceeded. Below H* there is a central stationary core; above H* we observe the onset of additional axial shear associated wit...
متن کاملInteractive Visualization of Three Dimensional Cellular Automata
This paper summarizes results of a project on a massively parallel computer. The project encompasses time evolution of a complex system, data analysis of the relevant measures and interactive visualization of the time dependent emerging structures within an integrated tool. We develop visualization and interpretation models for the general class of 3D and (3 + 1)D multi{state elds, represented ...
متن کاملA Lattice - Based Cellular Automata Modeling Approach for Granular Flow Lubrication
Liquid lubricants break down at extreme temperatures and promote stiction in micro-/ nanoscale environments. Consequently, using flows of solid granular particles as a “dry” lubrication mechanism in sliding contacts was proposed because of their ability to carry loads and accommodate surface velocities. Granular flows are highly complex flows that in many ways act similar to fluids, yet are dif...
متن کاملThe stress tensor in a two-dimensional granular shear flow
A computer simulation is used to make a detailed study of the stress tensor in a simple shear flow of two-dimensional disks. The stresses are shown to arise from two momentum-transfer mechanisms : the ‘streaming ’ or kinetic mode, by which momentum is carried by particles as they move through the bulk material; and the collisional mode, by which momentum is transferred from one point to another...
متن کاملMorphologies of three-dimensional shear bands in granular media.
We present numerical results on spontaneous symmetry breaking strain localization in axisymmetric triaxial shear tests of granular materials. We simulated shear band formation using the three-dimensional distinct element method with spherical particles. We demonstrate that the local shear intensity, the angular velocity of the grains, the coordination number, and the local void ratio are correl...
