Transient motions of elasto-viscoplastic thixotropic materials subjected to an imposed stress field and to stress-based free-surface boundary conditions
(Elsevier B.V., 2016-12-01)
In the present work, we present an approach to handle transient flows of elasto-viscoplastic thixotropic (EVPT) materials under the action of the gravity force field and subjected to free-surface boundary conditions that ...
The avalanche effect of an elasto-viscoplastic thixotropic material on an inclined plane
(Elsevier B.V., 2017-09-01)
The so-called avalanche effect is one of the fingerprints of thixotropic materials. This self-reinforcing process where the decrease in viscosity, due to a rejuvenation process triggered by a stress field, induces a motion ...
Thixotropic Behavior of Oil-in-Water Emulsions Stabilized with Ethoxylated Amines at Low Shear Rates
(2019)
© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, WeinheimOil-in-water (O/W) emulsification is a lubricating pipeline method based on the reduction of the energy frictional loss produced during viscous flow. The flow behavior of ...
Normal and oblique drop impact of yield stress fluids with thixotropic effects
(Cambridge Univ Press, 2019-10-10)
Normal and oblique drop impact on a solid surface is numerically analysed for yield stress fluids. A rich diversity of results are generated as a consequence of the exploration of the inertial, elastic, plastic and thixotropic ...
Study of the colloidal stability and optical properties of sunscreen creams
(2019-01-01)
Sunscreen formulations containing inorganic/organic filters or mixture of them were synthesized by oil/water dispersion. The viscosity measurements show that sunscreen formulations are time-dependent non-Newtonian fluids. ...

Understanding thixotropic and antithixotropic behavior of viscoelastic micellar solutions and liquid crystalline dispersions. I. The model
(1999)
A simple model consisting of the Upper Convected Maxwell constitutive equation and a kinetic equation for destruction and construction of structure, first proposed by Fredrickson in 1970, is used here to reproduce the ...

Rheological properties of frozen concentrated orange juice (FCOJ) as a function of concentration and subzero temperatures
(Taylor & Francis Inc, 2007-01-01)
Data on flow properties of Frozen Concentrated Orange Juice (FCOJ) produced from oranges cv. Pera-Rio (65.04 Brix, 8.8% w/w pulp content, 2.5% w/w pectin, 3.84% citric acid, 1.293 g cm(-3)) from -18 to 0 degrees C were ...
