Experiments and simulations of a gravitational granular flow instability.
An instability is observed as a layer of dense granular material positioned above a layer of air falls in a gravitational field [Phys. Rev. Lett. 99, 048001 (2007)]. A characteristic pattern of fingers emerges along the interface defined by the grains, and a transient coarsening of the structure is caused by a coalescence of neighboring fingers. The coarsening is limited by the production of ne...
متن کاملGranular Rayleigh-Taylor instability: experiments and simulations.
A granular instability driven by gravity is studied experimentally and numerically. The instability arises as grains fall in a closed Hele-Shaw cell where a layer of dense granular material is positioned above a layer of air. The initially flat front defined by the grains subsequently develops into a pattern of falling granular fingers separated by rising bubbles of air. A transient coarsening ...
متن کاملSteady Flow and its Instability of Gravitational Granular Flow
Granular matter consists of a large number of macroscopic particles; the thermal noise has no effect on the particle motion and the interactions are dissipative. These features make the granular flow very different from molecular fluids. One of the simplest situations to see the complex behavior of granular flow is the gravitational granular flow on a slope. When the inclination angle is small ...
متن کاملA granular Rayleigh-Taylor instability: experiments and simulations
A granular instability is studied experimentally and numerically as a packing of dense granular material positioned above a gap of air falls under gravity in a closed Hele-Shaw cell; a granular analog of the RayleighTaylor instability. A characteristic pattern of fingers separated by dilute bubbles emerges along the interface, and, in contrast to the classical, hydrodynamic instability, a trans...
متن کاملA Novel Indicator to Predict the Onset of Instability of a Gravitational Flow on a Slope
In order to present a quantitative indicator for the onset of instability, in this paper, the critical points of a stratified gravitational flow on a slope are found and analyzed. These points are obtained by means of the solution of the two-dimensional Navier-Stokes equations via the standard Arakawa-C finite-difference method. Results show that in the marginal Richardson numbers, the critical...
