Geometric Origin of Macroscopic Alignment in Granular Flows
Christopher Harper, Eric C. P. Breard, George W. Bergantz +1
Predicting the nematic alignment of nonspherical particles in sheared granular flows is essential for understanding the rheology, packing, and constitutive response of dense partic…
Diffusion compaction coupling controls pore pressure dynamics in granular fluid flows
Eric C. P. Breard, Claudia Elijas Parra, Mattia de' Michieli Vitturi
Excess pore pressure in granular--fluid mixtures can transiently suppress frictional contacts and dramatically enhance flow mobility, yet its evolution is commonly modeled using co…
The role of compressional dynamics in setting the scale-dependent rheology of granular flows: Application to the emergence of thin layer stability
Christopher Harper, Josef Dufek, Eric C. P. Breard
One great challenge of modeling granular systems lies in capturing the rheologic dependencies on scale. For example, there are marked differences between quasi-static, intermediate…
On the settling and clustering behavior of polydisperse gas-solid flows with application to pyroclastic density currents
E. Foster, E. C. P. Breard, S. Beetham
Sedimenting flows occur in a range of society-critical systems, such as circulating fluidized bed reactors and pyroclastic density currents (PDCs), the most hazardous volcanic proc…
Basal force fluctuations and granular rheology: Linking macroscopic descriptions of granular flows to bed forces with implications for monitoring signals
P. J. Zrelak, Eric C. P. Breard, Josef Dufek
Granular flows are ubiquitous in nature with single flows traversing a wide range of dynamic conditions from initiation to deposition. Many of these flows are responsible for signi…
The Rheology of Granular Mixtures with Varying Size, Density, Particle Friction and Flow Geometry
Eric C. P Breard, Luke Fullard, Josef Dufek
Employing the discrete element method, we study the rheology of dense granular media mixtures, varying in size, density, and frictional properties of particles, across a spectrum f…
