Pressure-driven flow of suspensions: simulation and theory
Dynamic simulations of the pressure-driven flow in a channel of a non-Brownian suspension at zero Reynolds number were conducted using Stokesian Dynamics. The simulations are for a monolayer of…
Microstructure of strongly sheared suspensions and its impact on rheology and diffusion
The effects of Brownian motion alone and in combination with an interparticle force of hard-sphere type upon the particle configuration in a strongly sheared suspension are analysed. In the limit…

The rheological behavior of a monodisperse suspension of non-Brownian particles undergoing simple shear flow in the presence of a weak interparticle force is studied using accelerated Stokesian…
STOKESIAN DYNAMICS
Particles suspended or dispersed in a fluid medium occur in a wide variety of natural and man-made s ttings, e.g. slurries, composite materials, ceramics, colloids, polymers, proteins, etc. The…
The rheology of concentrated suspensions of spheres in simple shear flow by numerical simulation
The newly developed simulation method known as Stokesian dynamics is used to investigate the rheological behaviour of concentrated suspensions. Both the detailed microstructure (e.g.…

A general method for computing the hydrodynamic interactions among N suspended particles, under the condition of vanishingly small particle Reynolds number, is presented. The method accounts for both…
Dispersion in fixed beds
A macroscopic equation of mass conservation is obtained by ensemble-averaging the basic conservation laws in a porous medium. In the long-time limit this ‘macro-transport’ equation takes the form of…
Shear thickening in colloidal dispersions
Shampoos, paints, cements, and soft body armor that stiffens under impact are just a few of the materials whose rheology is due to the change in viscosity that occurs when colloidal fluids experience…
Structure, diffusion and rheology of Brownian suspensions by Stokesian Dynamics simulation
- David R. Foss, J. Brady
- PhysicsJournal of Fluid Mechanics
- 25 March 2000
The non-equilibrium behaviour of concentrated colloidal dispersions is studied using Stokesian Dynamics, a molecular-dynamics-like simulation technique for analysing suspensions of particles immersed…
The rheological behavior of concentrated colloidal dispersions
- J. Brady
- Physics
- 1 July 1993
A simple model for the rheological behavior of concentrated colloidal dispersions is developed. For a suspension of Brownian hard spheres there are two contributions to the macroscopic stress: a…
