Role of Couple Stresses in Shallow Granular Flows down a Bumpy Incline
نویسنده
چکیده
We extend the micropolar fluid theory of Hayakawa and Mitarai, et al. [PRL 88, 174301 (2002)] to dense, relatively shallow flows of spherical grains down an inclined plane on which spherical bumps have been affixed. We update the model of Louge [PRE 67, 061303 (2003)], and show the role played by couple stresses in establishing the solid volume fraction in the core of the flow.

Dense Granular Flows down Inclines
Dense granular flows down inclines continue to defy understanding. However, the last three decades have witnessed progress in techniques and approaches that have moved the field closer to achieving ab initio predictions of practical relevance. Difficulties arise for three principal reasons. First, because granular flows dissipate mechanical energy on the particle scale, regions featuring a subs...
متن کاملContinuum theory of partially fluidized granular flows.
A continuum theory of partially fluidized granular flows is developed. The theory is based on a combination of the equations for the flow velocity and shear stresses coupled with the order-parameter equation which describes the transition between the flowing and static components of the granular system. We apply this theory to several important granular problems: avalanche flow in deep and shal...
متن کاملCollisional Granular Flows with and without Gas Interactions in Microgravity
We illustrate the convenience of a long-lasting microgravity environment to study flows of granular materials with and without gas interaction. We consider collisional granular flows of nearly elastic identical spheres in an axisymmetric Couette channel featuring two cylindrical moving bumpy boundaries and two flat walls. We review governing equations for these flows, illustrate their solutions...
متن کاملGranular forces from steady and avalanche flows on a wall-like obstacle: contribution to avalanche dam design
The present paper deals with the hydrodynamic force from granular streams overflowing a wall-like obstacle. An analytical continuum model is proposed to derive this force both for steady and unsteady flow conditions. The force derived from the continuum model is successfully compared to the time-averaged force from discrete numerical simulations of free-surface granular flows down an incline an...
متن کاملTransverse instability of avalanches in granular flows down an incline.
Avalanche experiments on an erodible substrate are analyzed using the "partial fluidization" model of dense granular flows. The model identifies a family of propagating solitonlike avalanches with shape and velocity controlled by the inclination angle and the depth of the substrate. At high inclination angles, the solitons display a transverse instability, followed by coarsening and fingering s...
