Non-Newtonian behaviour of flocculated suspensions
Abstract
A theoretical model is proposed to describe the non-Newtonian behaviour of flocculated suspensions. This behaviour is supposed to originate from the immobilized fluid between the particles which forms flocs. A self-consistent field approximation is used to estimate the mean radius of flowing flocs in a simple shear field, and, as a consequence, the amount of immobilized fluid in flocs. Then a rheological law is proposed in which four fixed physical parameters are involved.
