Absorbing-state transitions in particulate systems under spatially varying driving
Bhanu Prasad Bhowmik, Christopher Ness
We study the absorbing state transition in particulate systems under spatially inhomogeneous driving using a modified random organization model. For smoothly varying driving the st…
Scaling description of frictionless dense suspensions under inhomogeneous flow
Bhanu Prasad Bhowmik, Christopher Ness
Predicting the rheology of dense suspensions under inhomogeneous flow is crucial in many industrial and geophysical applications, yet the conventional `' framework is limited…
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…
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…
Linking particle properties to paste extrusion flow characteristics using discrete element simulations
Christopher Ness, Jin Y. Ooi, Jin Sun +4
Extrusion is a widely used process for forming pastes into designed shapes, and is central to the manufacture of many industrial products. The extrusion through a square-entry die…
Flow regime transitions in dense non-Brownian suspensions: rheology, microstructural characterisation and constitutive modelling
Christopher Ness, Jin Sun
Shear flow of dense, non-Brownian suspensions is simulated using the discrete element method, taking particle contact and hydrodynamic lubrication into account. The resulting flow…
