The. Moreover, we show that the ill-posed domain defined by Barker et al.(J. Fluid Mech.,
vol. 779, 2015, pp. 794–818) transforms into a domain where the flow is unstable but …

Local rheology relation with variable yield stress ratio across dry, wet, dense, and dilute granular flows

T Pähtz, O Durán, DN De Klerk, I Govender… - Physical review letters, 2019 - APS
Dry, wet, dense, and dilute granular flows have been previously considered fundamentally
different and thus described by distinct, and in many cases incompatible, rheologies. We …

Local rheological measurements in the granular flow around an intruder

A Seguin, C Coulais, F Martinez, Y Bertho, P Gondret - Physical Review E, 2016 - APS
The rheological properties of granular matter within a two-dimensional flow around a moving
