Abstract

The flow properties of dispersions are a function of both particle number density and interparticle potential. At high number densities suspensions change from fluid-like behaviour to solid-like. The number density where this transition occurs is controlled by the shape of the interparticle potential function. The material state is clearly indicated from the rheological measurements. Wave propagation, stress relaxation and continuous shear viscometry have been used to study a variety of suspensions of monodisperse particles. Hard sphere, weakly attractive and strongly repulsive systems are discussed.
