Non-Newtonian behaviour of suspensions and emulsions: Review of different mechanisms

Abstract

The mechanisms of non-Newtonian behaviour of suspensions and emulsions in steady shear flow are reviewed. The review is divided into two parts. In the first part, the mechanisms of non-Newtonian behaviour in suspensions and emulsions composed of Newtonian matrix are reviewed. Both dilute and concentrated systems are discussed. In the second part, the mechanisms of non-Newtonian behaviour in suspensions and emulsions composed of non-Newtonian matrix are reviewed. Where appropriate, mathematical models describing the rheology are included.

Keywords: Emulsions; Non-Newtonian; Rheology; Shear-thickening; Shear-thinning; Suspensions; Viscosity.
