Non-Newtonian behaviour of suspensions and emulsions: Review of different mechanisms
Rajinder Pal
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. • The mechanisms for non-Newtonian behaviour in suspensions and emulsions are reviewed. • Dilute, concentrated, and highly concentrated systems are considered. • Suspensions and emulsions with Newtonian and non-Newtonian matrices are reviewed. • Shear-thinning, shear-thickening, and yield stress in suspensions and emulsions are discussed and explained.
