A Weakly Non-hydrostatic Shallow Model for Dry Granular Flows
(Springer, 2021)
A non-hydrostatic depth-averaged model for dry granular flows is proposed, taking into account vertical acceleration. A variable friction coefficient based on the μ(I) rheology is considered. The model is obtained from ...

Dilatancy in dry granular flows with a compressible μ(I) rheology
(Elsevier, 2021)
Dilatancy plays a key role in mixtures of grains and fluid but is poorly investigated in dry granular flows. These flows may however dilate by more than 10% in granular column collapses. We investigate here dilatancy effects ...
