Non-local rheology in dense granular flows: Revisiting the concept of fluidity
The aim of this article is to discuss the concepts of non-local rheology and fluidity, recently
introduced to describe dense granular flows. We review and compare various approaches …

Continuum modelling and simulation of granular flows through their many phases
S Dunatunga, K Kamrin - Journal of Fluid Mechanics, 2015 - cambridge.org
We propose and numerically implement a constitutive framework for granular media that
allows the material to traverse through its many common phases during the flow process …

Microscopic description of the granular fluidity field in nonlocal flow modeling
A recent granular rheology based on an implicit “granular fluidity” field has been shown to
quantitatively predict many nonlocal phenomena. However, the physical nature of the field …

Disentangling the free-fall arch paradox in silo discharge
Several theoretical predictions of the mass flow rate of granular media discharged from a
silo are based on the spontaneous development of a free-fall arch region, the existence of …

Archimedes' law explains penetration of solids into granular media
W Kang, Y Feng, C Liu, R Blumenfeld - Nature communications, 2018 - nature.com
Understanding the response of granular matter to intrusion of solid objects is key to
modelling many aspects of behaviour of granular matter, including plastic flow. Here we …

Critical scaling near the yielding transition in granular media
We show that the yielding transition in granular media displays second-order critical-point
scaling behavior. We carry out discrete element simulations in the low-inertial-number limit …
