▪ Abstract We review the fluid mechanics and rheology of dense suspensions, emphasizing investigations of microstructure and total stress. “Dense” or “highly concentrated” suspensions are those in which the average particle separation distance is less than the particle radius. For these suspensions, multiple-body interactions as well as two-body lubrication play a significant role and the rheology is non-Newtonian. We include investigations of multimodal suspensions, but not those of suspensions with dominant nonhydrodynamic interactions. We consider results from both physical experiments and computer simulations and explore scaling theories and the development of constitutive equations.read more

Unifying suspension and granular rheology.
TL;DR: Dense suspension and granular media are unified under a common framework and the results are shown to be compatible with classical empirical models of suspension rheology and provide a clear determination of constitutive laws close to the jamming transition.

Simulating microscopic hydrodynamic phenomena with dissipative particle dynamics
PJ Hoogerbrugge,J.M.V.A. Koelman +1 more
Abstract: We present a novel method for simulating hydrodynamic phenomena. This particle-based method combines features from molecular dynamics and lattice-gas automata. It is shown theoretically as well as in simulations that a quantitative description of isothermal Navier-Stokes flow is obtained with relatively few particles. Computationally, the method is much faster than molecular dynamics, and the at same time it is much more flexible than lattice-gas automata schemes.

The effect of Brownian motion on the bulk stress in a suspension of spherical particles
TL;DR: In this article, the effect of Brownian motion on the probability density of the separation vector of rigid spherical particles in a dilute suspension is investigated and an explicit expression for this leading approximation is constructed in terms of hydrodynamic interactions between pairs of particles.
