Non-Local Particle Flows Become Local When Considering Dissipative Stress
Martin Trulsson
Dense granular and suspension flows under inhomogeneous shear exhibit persistent particle motion in regions where the local yield criterion is subcritical, an apparent breakdown of…
Mapping the limits of equilibrium in sheared granular liquid crystals
Jacopo Bilotto, Martin Trulsson, Jean-François Molinari
Athermal elongated particles are well-known to follow Jeffery orbits when sheared in viscous fluids. It is less clear if similar orbits appear in dense granular flows. We show that…
Shear flow of frictional spheroids: Comparison between elongated and flattened particles
Jacopo Bilotto, Martin Trulsson, Jean-François Molinari
The rheology of dense granular shear flows is influenced by friction and particle shape. We investigate numerically the impact of non-spherical particle geometries under shear on p…
Shear jamming transition in alternating shear rotation for frictional and frictionless suspensions
Pappu Acharya, Martin Trulsson
Alternating shear rotations in dense suspensions have recently shown the ability to reduce both viscosity and dissipation per strain (at a fixed global shear rate). Here, we study…
A strong-coupling effective-field theory for asymmetrically charged plates with counterions only
L. Samaj, E. Trizac, M. Trulsson
We are interested in rationalizing the phenomenon of like-charge attraction between charged bodies, such as a pair of colloids, in the strong coupling regime. The two colloids are…
