A comprehensive review is presented of the physical behavior of yield stress materials in
soft condensed matter, which encompasses a broad range of materials from colloidal …

Yield stress fluid flows occur in a great many operations and unit processes within the oil
and gas industry. This paper reviews this usage within reservoir flows of heavy oil, drilling …

The influence of the solvent type on the rheological properties of Carbopol® NF 980
dispersions in water and in water/glycerol solutions is investigated. The material formulation …

The review presents current research results for Carbopol-based microgels as yield-stress
materials, covering three aspects: chemical, physical and rheological. Such a joint three …

The relationship between the thixotropic mechanism and the macroscopic thixotropic
strength can be clarified by analyzing the changes in microstructure and pores in the loess …

A constitutive model for structured fluids is presented. Its predictive capability includes
thixotropy, viscoelasticity and yielding behavior. It is composed by two differential equations …

A constitutive model for elasto-viscoplastic thixotropic materials is proposed. It consists of
two differential equations, one for the stress and the other for the structure parameter, a …

The rheological behavior of cement slurries is important in trying to prevent and eliminate
gas-migration related problems in oil well applications. In this paper, we review the …

To describe the macroscopic rheological behavior of thixotropic elasto-visco-plastic (TEVP)
materials, phenomena that take place in their microstructure must be accounted for. To this …

The literature on thixotropy modeling is reviewed, with particular emphasis on models for
yield stress materials that possess elasticity. The various possible approaches that have …
