Taylor-Couette flow of hard-sphere suspensions: Overview of current understanding
Lina Baroudi, Madhu V. Majji, Stephen Peluso +1
Although inertial particle-laden flows occur in a wide range of industrial and natural processes, there is both a lack of fundamental understanding of these flows and continuum-lev…
-core analysis of shear-thickening suspensions
Omer Sedes, Bulbul Chakraborty, Hernan A. Makse +1
Shear thickening of suspensions is studied by discrete-particle simulation, accounting for hydrodynamic, repulsive, and contact forces. The contact forces, including friction, are…
Microstructure of the near-wall layer of filtration-induced colloidal assembly
Mohand Larbi Mokrane, Térence Desclaux, Jeffrey F. Morris +2
This paper describes an experimental study of filtration of a colloidal suspension using microfluidic devices. A suspension of micrometer-scale colloids flows through parallel slit…
Sediment creep triggered by porous flow
Morgane Houssais, Charles Maldarelli, Jeffrey F. Morris
Quasi-2D experiments of a submerged sediment layer creeping downward were performed, varying the channel tilt and a porous flow under the respective thresholds for yielding. Logari…
Interaction network analysis in shear thickening suspensions
Marcio Gameiro, Abhinendra Singh, Lou Kondic +2
Dense, stabilized, frictional particulate suspensions in a viscous liquid undergo increasingly strong continuous shear thickening (CST) as the solid packing fraction, , increase…
Shear jamming and fragility in dense suspensions
Ryohei Seto, Abhinendra Singh, Bulbul Chakraborty +2
The phenomenon of shear-induced jamming is a factor in the complex rheological behavior of dense suspensions. Such shear-jammed states are fragile, i.e., they are not stable agains…
Soil granular dynamics on-a-chip: fluidization inception under scrutiny
Morgane Houssais, Charles Maldarelli, Jeffrey F. Morris
Predicting rapid and slower soil evolution remains a scientific challenge. This process involves poorly understood aspects of disordered granular matter and dense suspension dynami…
From yielding to shear jamming in a cohesive frictional suspension
Abhinendra Singh, Sidhant Pednekar, Jaehun Chun +2
Simulations are used to study the steady shear rheology of dense suspensions of frictional particles exhibiting discontinuous shear thickening and shear jamming, in which finite-ra…
Global topology of contact force networks: new insight into shear thickening suspensions
Lance E. Edens, Sidhant Pednekar, Jeffrey F. Morris +3
Highly concentrated or 'dense" particle suspensions can undergo a sharp increase in viscosity, or shear thickening, under applies stress. Understanding the fundamental features lea…
Microscopic origin of frictional rheology in dense suspensions: correlations in force space
Jetin E. Thomas, Kabir Ramola, Abhinendra Singh +3
We develop a statistical framework for the rheology of dense, non-Brownian suspensions, based on correlations in a space representing forces, which is dual to position space. Worki…
Bidisperse and polydisperse suspension rheology at large solid fraction
Sidhant Pednekar, Jaehun Chun, Jeffrey Morris
At the same solid volume fraction, bidisperse and polydisperse suspensions display lower viscosities, and weaker normal stress response, compared to monodisperse suspensions. The r…
Pore cross-talk in colloidal filtration
Olivier Liot, Akash Singh, Patrice Bacchin +3
Blockage of pores by particles is found in many processes, including filtration and oil extraction. We present filtration experiments through a linear array of ten channels with on…
A constitutive model for simple shear of dense frictional suspensions
Abhinendra Singh, Romain Mari, Morton M. Denn +1
Discrete particle simulations are used to study the shear rheology of dense, stabilized, frictional particulate suspensions in a viscous liquid, toward development of a constitutiv…
Shear-induced organization of forces in dense suspensions: signatures of discontinuous shear thickening
Sumantra Sarkar, Elan Shatoff, Kabir Ramola +3
Dense suspensions can exhibit an abrupt change in their viscosity in response to increasing shear rate. The origin of this discontinuous shear thickening (DST) has been ascribed to…
