Abstract The purpose of this paper was determining the effects two nanoparticles additions in a commercial epoxy coating system on rheology characterization. Two kinds hybrid organic–inorganic silicates (benzytallowdimethylammonium salts with bentonite) were studied, APA, C 14-16 organic chain and, HT, 2-4 chain. A 2 factorial design, categorical nanoparticules factors applied. experimental dat...

We report on theoretical and experimental studies describing the buoyancy-driven ascent of a Taylor long drop in circular vertical pipe where descending fluid is Newtonian, ascending non-Newtonian yield shear thinning described by three-parameter Herschel–Bulkley model, including Ostwald–de Waele model as special case for zero yield. Results Ellis are included to provide more realistic descript...

Flows of dense emulsions show many complex features among which long range nonlocal effects pose a problem for macroscopic characterization. In order to get around this problem, we study the flows of several dense emulsions, with droplet size ranging from 0.3to40microm , in a wide-gap Couette geometry. We couple macroscopic rheometric experiments and local velocity measurements through magnetic...

The aim of this research was to assess the effect of fat type and concentration as well as the continuous phase viscosity on the rheological properties of an oil-in-water (O/W) emulsion. Thus, sunflower oil and tallow fat were used as the dispersed phase of the emulsion both at 10 and 50% (w/v) and CMC solutions (at 0.1, 0.3 and 0.5% w/v) were acted as the continuous phase. CMC solutions and em...

Pistachio paste is produced from ground roasted kernel. This study focused on the influence of the milling process on colloidal stability, rheological behavior and color of pistachio paste. The colloidal stability of pistachio paste samples increased with a reduction of particle size from 31.4 to 15.10µm. The Herschel-Bulkley model was found to be the best model to describe the flow behavior of...
