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…
The effect of a wall on the interaction of two spheres in shear flow: Batchelor-Green theory revisited
Itzhak Fouxon, Boris Rubinstein, Zhouyang Ge +2
The seminal Batchelor-Green's (BG) theory on the hydrodynamic interaction of two spherical particles of radii a suspended in a viscous shear flow neglects the effect of the boundar…
Droplets in homogeneous shear turbulence
Marco E. Rosti, Zhouyang Ge, Suhas S. Jain +2
We simulate the flow of two immiscible and incompressible fluids separated by an interface in a homogeneous turbulent shear flow at a shear Reynolds number equal to 15200. The visc…
Effective slip over partially filled microcavities and its possible failure
Zhouyang Ge, Hanna Holmgren, Martin Kronbichler +2
Motivated by the emerging applications of liquid-infused surfaces (LIS), we study the drag reduction and robustness of transverse flows over two-dimensional microcavities partially…
Integral representation of channel flow with interacting particles
Itzhak Fouxon, Zhouyang Ge, Luca Brandt +1
We construct a boundary integral representation for the low-Reynolds-number flow in a channel in the presence of freely-suspended particles (or droplets) of arbitrary size and shap…
An efficient mass-preserving interface-correction level set/ghost fluid method for droplet suspensions under depletion forces
Zhouyang Ge, Jean-Christophe Loiseau, Outi Tammisola +1
Aiming for the simulation of colloidal droplets in microfluidic devices, we present here a numerical method for two-fluid systems subject to surface tension and depletion forces am…
