Global Organization of Three-Dimensional, Volume-Preserving Flows: Constraints, Degenerate Points, and Lagrangian Structure
Bharath Ravu, Guy Metcalfe, Murray Rudman +2
Global organization of 3-dimensional (3D) Lagrangian chaotic transport is difficult to infer without extensive computation. For 3D time-periodic flows with one invariant we show ho…
Analysis of granular rheology in a quasi-two-dimensional slow flow by means of discrete element method based simulations
Ashish Bhateja, Devang V. Khakhar
The steady flow of spherical particles in a rectangular bin is studied using the Discrete Element Method (DEM) for different flow rates of the particles from the bin, in the slow f…
Rheology of dense granular flows in two dimensions: Comparison of fully two-dimensional flows to unidirectional shear flow
Ashish Bhateja, Devang V. Khakhar
This work utilizes soft-particle discrete element simulations to examine the rheology of steady two-dimensional granular flows with reference to a unidirectional shear flow, which…
A sidewall friction driven ordering transition in granular channel flows: Implications for granular rheology
Sandip Mandal, D. V. Khakhar
We report a transition from a disordered state to an ordered state in the flow of nearly mono-disperse granular matter flowing in an inclined channel with a bumpy base, in discrete…
Surface Granular flows: Two Related Examples
D. V. Khakhar, Ashish V. Orpe, J. M. Ottino
Granular surface flows are common in industrial practice and natural systems, however, theoretical description of such flows is at present incomplete. Two prototype systems involvi…
Solid-fluid transition in a granular shear flow
Ashish V. Orpe, D. V. Khakhar
The rheology of a granular shear flow is studied in a quasi-2d rotating cylinder. Measurements are carried out near the midpoint along the length of the surface flowing layer where…
