Rheology of bidisperse suspensions at the colloidal-to-granular transition
Xuan Li, John R. Royer, Christopher Ness
We use particle-based simulation to study the rheology of dense suspensions comprising mixtures of small colloids and larger grains, which exhibit shear thinning at low shear rates…
Simulating the rheology of dense suspensions using pairwise formulation of contact, lubrication and Brownian forces
Xuan Li, John R. Royer, Christopher Ness
Dense suspensions of solid particles in viscous liquid are ubiquitous in both industry and nature, and there is a clear need for efficient numerical routines to simulate their rheo…
Sizing multimodal suspensions with differential dynamic microscopy
Joe J Bradley, Vincent A Martinez, Jochen Arlt +2
Differential dynamic microscopy (DDM) can be used to extract mean particle size from videos of suspensions. However, many suspensions have multimodal particle size distributions (P…
Impact of granular inclusions on the phase behavior of colloidal gels
Yankai Li, John R. Royer, Jin Sun +1
Colloidal gels formed from small attractive particles are commonly used in formulations to keep larger components in suspension. However, despite extensive work characterizing unfi…
Rheological design of thickened alcohol-based hand rubs
Andreia F Silva, Tiffany A Wood, Daniel J M Hodgson +4
The handleability and sensory perception of hand sanitisers by consumers affect the hygiene outcome. Spillage may result in under-dosing and poor sensory properties can lead to und…
Flow-Switched Bistability in a Colloidal Gel with Non-Brownian Grains
Yujie Jiang, Soichiro Makino, John R. Royer +1
We show that mixing a colloidal gel with larger, non-Brownian grains generates novel flow-switched bistability. Using a combination of confocal microscopy and rheology, we find tha…
