Understanding thixotropic and antithixotropic behavior of viscoelastic micellar solutions and liquid crystalline dispersions. I. The model
Abstract 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, isExpand
Effect of cholesterol and triglycerides levels on the rheological behavior of human blood
Important public health problems worldwide such as obesity, diabetes, hyperlipidemia and coronary diseases are quite common. These problems arise from numerous factors, such as hyper-caloric diets,Expand
Dynamics of worm-like micelles: the Cox–Merz rule
Abstract The viscoelastic behaviour of worm-like micelles in small-amplitude oscillatory, steady simple shear and uniaxial extensional flows are analyzed with a model that couples the Oldroyd-BExpand
On the shear banding flow of elongated micellar solutions
Abstract Under steady shear flow, elongated micellar solutions show shear stress saturation above a critical shear rate due to the formation of shear bands that result in non-homogeneous flow. LongExpand
Modeling asphaltene deposition in production pipelines
A multiphase (oil/gas/asphaltene/water) multicomponent hydrodynamic model is proposed to represent the phenomenon of asphaltene deposition in producing wells. The model is based on the assumptionExpand
Capillary rheometry of micellar aqueous solutions
Abstract In this work, the capillary flow of wormlike micellar solutions was studied in detail. Flow curves obtained with capillaries of different sizes for surfactant aqueous solutions at variousExpand
On the rheological modeling of associative polymers
The viscoelastic behavior of a commercial hydrophobic alkali-soluble emulsion (HASE) associative polymer in small-amplitude oscillatory, steady, and unsteady simple-shear flows is analyzed with aExpand
A mathematical model for the reactive extrusion of methyl methacrylate in a co-rotating twin-screw extruder
A mathematical model for the reactive extrusion of methyl methacrylate (MMA) is presented. Key variables, such as pressure, temperature, residence time, filling ratio, number-average, andExpand
Rheological modelling of complex fluids: A transient network model with microstates
In this work, the dynamics of a transient network is analyzed with a model that includes two coupled kinetic processes to describe the rheological behavior of complex fluids. Five microstates areExpand
