Piv study of mixing characteristics in a stirred vessel with a non-Newtonian fluid [PDF]
, 2012 PIV is used to analyze the flow induced by a Rushton turbine in a shear-thinning fluid, at constant input power, constant impeller velocity but different concentrations. The rheology of each shear-thinning fluid is first addressed.

Laminar flow in three-dimensional square-square expansions [PDF]
, 2011 In this work we investigate the three-dimensional laminar flow of Newtonian and viscoelastic fluids through square–square expansions. The experimental results obtained in this simple geometry provide useful data for benchmarking purposes in complex three-

Aggregation of silica nanoparticles in concentrated suspensions under turbulent, shear and extensional flows. [PDF]
, 2013 The production of nanoparticles in concentrated suspensions requires strict control of the stability of the systems which are strongly influenced by the physico-chemical properties and the hydrodynamic conditions they are placed in. This study deals with

Numerical and Experimental Investigation of a Non-Newtonian Flow in a Collapsed Elastic Tube
Applied Rheology, 2012 Simulations are performed to investigate the flow of a shear-thinning, non-Newtonian fluid in a collapsed elastic tube and comparisons are made with experimental data. The fluid is modeled by means of the Bird- Carreau viscosity law.

AIP Advances, 2021 The theory of the so-called Rayleigh–Plateau instability of fluid jets has been widely studied and can be used to predict the breakup length of liquid jets. Recently, in the work of Rosello et al. [J. Fluids Eng. 140(3), 031202 (2018)], the linear theory

Influence of the Polarity of the Electric Field on Electrorheometry [PDF]
, 2019 Uniaxial extensional flow is a canonical flow typically used in rheological characterization to provide complementary information to that obtained by imposing simple shear flow.
