“…which agrees with the results up to four decimal places. The viscosity expression for polydisperse non-colloidal suspensions derived by Mwasame et al [38][39][40] uses the size distribution of the agglomerates in the form of abscissa (m i ) and weights (ω i ) of the quadrature,…”

“…While successfully applied to model a range of thixotropic and viscoelastic behavior in suspensions of fumed silica and human blood, 36 the oversimplistic nature of the monodisperse assumption fails to adequately represent the agglomerate distribution and significantly overpredicts the agglomerate sizes when compared with independent microstructural measurements. 37 Polydisperse particles typically pack at a much higher volume fractions (ϕ mono max < ϕ poly max ), and Mwasame et al [38][39][40] proposed corrections in relative viscosity relationships that can be directly incorporated into an improved approach.…”

An improved population balance‐based rheological constitutive framework for polydisperse aggregating suspensions is derived by incorporating detailed models for orthokinetic and perikinetic aggregation and shear breakage processes. The framework accounts for critical properties such as dynamic arrest, viscoelasticity, kinematic hardening, thixotropy, and yield stress to generate a full range of thixotropic elasto‐viscoplastic (TEVP) response. Additionally, the model is thermodynamically consistent because the dynamics and timescales are completely determined by internal structural and kinetic variables. The model connects the rheological response to the structural descriptors such as the size distribution of agglomerates, mean sizes, fractal dimension, and agglomerate volume fraction. Predictions are compared against a wide range of shear rheology measurements data for model thixotropic suspensions of fumed silica and carbon black, including large amplitude oscillatory shear (LAOS), as well as ultra‐small angle neutron scattering under steady shear (Rheo‐uSANS).

This review deals with non-Brownian (non-colloidal) suspension rheology; experimental and computational studies are compared where possible. The matrix fluids are Newtonian, and the rigid particles have an aspect ratio close to one. Volume fractions up to and including 0.5 are considered. Shearing and extensional flows are discussed; the former are fairly well understood, but the latter are not prominent in the literature. Unsteady and oscillatory flows are surveyed; more work is needed in this area. Finally some attempts to find constitutive models are discussed, and an empirically based suggestion based on a modified Reiner-Rivlin model is described.
