Dense Suspensions in Rotary Shear
Naveen Kumar Agrawal, Zhouyang Ge, Martin Trulsson +2
We introduce a novel unsteady shear protocol, which we name Rotary Shear (RS), where the flow and vorticity directions are continuously rotated around the velocity gradient directi…
Rheology of periodically sheared suspensions undergoing reversible-irreversible transition
Zhouyang Ge, Gwynn J. Elfring
The rheology of non-colloidal suspensions under cyclic shear is studied numerically. The main findings are a strain amplitude () dependent response in the shear stress and sec…
Irreversibility and rate dependence in sheared adhesive suspensions
Zhouyang Ge, Raffaella Martone, Luca Brandt +1
Recent experiments report that slowly-sheared noncolloidal particle suspensions can exhibit unexpected rate()-dependent complex viscosities in oscillatory shear, despite a const…
Weakly adhesive suspension shows rate-dependence in oscillatory but not steady shear flows
Zhouyang Ge, Raffaella Martone, Luca Brandt +1
We report rheological measurements of a noncolloidal particle suspension in a Newtonian solvent at 40% solid volume fraction. An anomalous, frequency-dependent complex viscosity is…
Implementation note on a minimal hybrid lubrication/granular dynamics model for dense suspensions
Zhouyang Ge, Luca Brandt
We describe and summarize a class of minimal numerical models emerged from recent development of simulation methods for dense particle suspensions in overdamped linear flows. The m…
