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 …

A novel approach for modeling the mechanical behavior of thixotropic viscoplastic fluids is
presented. Non-monotonic flow curves, stress overshoot during microstructure breakdown …

A new apparent viscosity function for shear thickening fluids is proposed, contemplating the
three characteristic regions typically exhibited by these materials: slight shear thinning at low …

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 …

Three hot break tomato pastes were investigated to determine the effect of their
characteristics on the properties of tomato ketchup, processed in an industrial-scale facility …

I present an alternative reasoning for the choice of characteristic quantities to be employed
in the non-dimensionalization of the governing equations of non-Newtonian fluid flow …

We examine the internal flow of viscoplastic liquids through ducts consisting of an abrupt
axisymmetric expansion followed by an abrupt contraction. Steady, inertialess numerical …

An experimental study of the flow of yield stress materials was conducted. The main goal
was to understand the relationship between the minimum axial pressure gradient required …

We extend our recent work on the creeping flow of a Bingham fluid in a lid-driven cavity, to
the study of inertial effects, using a finite volume method and the Papanastasiou …

This paper explores the flow behavior of a bi-dimensional lid-driven cavity filled with a
viscoplastic fluid. The results were obtained numerically using the moment representation of …
