A tentative geometrical description of static dilatancy in liquid foams: ordered 2D and 3D foams
Pierre Rognon, François Molino, Cyprien Gay
Liquid foams have been observed to behave like immersed granular materials in at least one respect: deformation tends to raise their liquid contents, a phenomenon called dilatancy.…

Dense granular flows: interpolating between grain inertia and fluid viscosity based constitutive laws
Pierre Rognon, Cyprien Gay
A scalar constitutive law was recently obtained for dense granular flows from a two-grain argument, both in the inertial regime (grain inertia) and in the viscous regime. As the re…

Dense granular flows: two-particle argument accounts for friction-like constitutive law with threshold
Pierre Rognon, Cyprien Gay
A scalar constitutive law is obtained for dense granular flows, both in the inertial regime where the grain inertia dominates, and in the viscous regime. Considering a pair of grai…
