Journal ArticleDOI
Modeling the thixotropic behavior of structured fluids
TL;DR: In this article, a novel approach for modeling the mechanical behavior of thixotropic viscoplastic fluids is presented, which involves two evolution equations, one for the stress and the other for the structure parameter.
Journal ArticleDOI
Thixotropic elasto-viscoplastic model for structured fluids
TL;DR: In this paper, a constitutive model for structured fluids is presented, which is composed of two differential equations, one for the stress and the other for the structure parameter, a scalar quantity that represents the structuring level of the fluid.
Journal ArticleDOI
A unified approach to model elasto-viscoplastic thixotropic yield-stress materials and apparent yield-stress fluids
TL;DR: In this article, a constitutive model for elasto-viscoplastic thixotropic materials is proposed, consisting of two differential equations, one for the stress and the other for the structure parameter, a scalar quantity that indicates the structuring level of the microstructure.
Journal ArticleDOI
A critical overview of elasto-viscoplastic thixotropic modeling
TL;DR: The literature on thixotropy modeling is reviewed in this paper, with particular emphasis on models for yield stress materials that possess elasticity, and various possible approaches that have been adopted to model the different facets of the mechanical behavior of this kind of materials are compared and discussed in detail.
Journal ArticleDOI
Bingham’s model in the oil and gas industry
TL;DR: In this paper, yield stress fluid flows occur in a great many operations and unit processes within the oil and gas industry, including heavy oil, drilling fluids and operations, wellbore cementing, hydraulic fracturing and some open-hole completions, sealing/remedial operations.
