We review thixotropy, its attributes, and accompanying rheological phenomena, such as
yielding, hysteresis in shear-rate ramps, the influence of rest time and viscosity bifurcation …

Wax deposition and gel formation have been crucial problems to the oil industries. The
deposition of waxes would lead to gelation which blocks flow in pipelines and interrupts …

The third edition of Bubbles, Drops, and Particles in Non-Newtonian Fluids provides
comprehensive coverage of the scientific foundations and the latest advances in particle …

Time-and rate-dependent material functions in non-Newtonian fluids in response to different
deformation fields pose a challenge in integrating different constitutive models into …

Guided by a series of discriminating rheometric tests, we develop a new constitutive model
that can quantitatively predict the key rheological features of waxy crude oils. We first …

In this work, we introduce a comprehensive machine-learning algorithm, namely, a
multifidelity neural network (MFNN) architecture for data-driven constitutive metamodeling of …

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 efficient development of extrusion-based 3D-printing requires flexibility in both
formulation-and process design. This task requires a fundamental understanding of the …

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 …
