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…
The rheology of Brownian suspensions
The viscosity of a suspension of spherical Brownian particles is determined by Stokesian dynamics as a function of the Peclet number. Several new aspects concerning the theoretical derivation of the…

A general method for computing the hydrodynamic interactions among an infinite suspension of particles, under the condition of vanishingly small particle Reynolds number, is presented. The method…
FIELD DEPENDENCE OF VISCOELASTIC PROPERTIES OF MR ELASTOMERS
A magnetoactive elastomer made of micronic carbonyl iron particles, structured in elongated clusters and embedded in a silicon elastomer matrix is studied under traction both in static and dynamic…

Magnetorheological suspensions are complex fluids which show a transition from a liquid behavior to a solid one upon application of a magnetic field. This transition is due to the the attractive…
Stokesian Dynamics simulation of Brownian suspensions
The non-equilibrium behaviour of concentrated colloidal dispersions is studied by Stokesian Dynamics, a general molecular-dynamics-like technique for simulating particles suspended in a viscous…
Dynamic simulation of sheared suspensions. I. General method
A general method is presented for simulating the dynamical behavior of a suspension of particles which interact through both hydrodynamic and nonhydrodynamic forces. In the molecular-dynamics-like…
Hydrodynamic transport properties of hard-sphere dispersions. I. Suspensions of freely mobile particles
- R. Phillips, J. Brady, G. Bossis
- Physics
- 1 December 1988
The hydrodynamic transport properties of hard-sphere dispersions are calculated for volume fractions (φ) spanning the dilute limit up to the fluid–solid transition at φ=0.49. Particle distributions…
