Abstract

A scaling relationship is developed for the asymptotic approach of the suspension viscosity of adhesive, rigid and non-Brownian particles to that of non-adhesive particles in the limit of high shear-rate where the agglomerates are broken down completely. The relationship is fitted to experimental data, for spherical particles, irregularly shaped particles and biconcave, discoid-shaped, hardened red blood cells. The relationship allows us to extract a proxy for the inter-particle adhesion force which, for the case of the blood cells, is in qualitative agreement with alternative force measurements in the literature.
