Characteristics of stratified flows of Newtonian/non-Newtonian shear-thinning fluids

open access: yes, 2017
Exact solutions for laminar stratified flows of Newtonian/non-Newtonian shear-thinning fluids in horizontal and inclined channels are presented. An iterative algorithm is proposed to compute the laminar solution for the general case of a Carreau non ...

Inertia effects in rheometrical flow systems Part 2: The balance rheometer [PDF]

open access: yes, 1976
The flow field of a linear viscoelastic fluid in the balance rheometer, taking fluid inertia into account, has been studied theoretically and an exact solution is given.

Modeling and numerical simulation of non-Newtonian arterial blood flow for mild to severe stenosis

open access: yesAlexandria Engineering Journal, 2023
The fundamental cause of coronary heart disease is thought to be atherosclerosis. Blood flow in arteries under plaque formation is widely studied using both experimental and theoretical methods in literature.

Micropropulsion and microrheology in complex fluids via symmetry breaking

open access: yes, 2012
Many biological fluids have polymeric microstructures and display non-Newtonian rheology. We take advantage of such nonlinear fluid behavior and combine it with geometrical symmetry-breaking to design a novel small-scale propeller able to move only in ...

Non-Newtonian effects in the peristaltic flow of a Maxwell fluid [PDF]

open access: yes, 2001
We analyzed the effect of viscoelasticity on the dynamics of fluids in porous media by studying the flow of a Maxwell fluid in a circular tube, in which the flow is induced by a wave traveling on the tube wall.

The Effect of Bubbles on Particle Migration in Non-Newtonian Fluids

open access: yesSeparations, 2021
The movement of the gas–liquid interface caused by the movement of the bubble position will have an impact on the starting conditions for particle migration.

Flow of Non-Newtonian Fluids

open access: yesNihon Reoroji Gakkaishi(Journal of the Society of Rheology, Japan), 1982
The present paper summarizes various problems on non-Newtonian fluid mechanics. Due to complex rheological behaviors of non-Newtonian fluids, constitutive equations have highly nonlinear character. As two approaches to obtain constitutive equations, continuum mechanics and molecular theory are described, and then a number of models are presented ...

Anisotropic Homogeneous Cosmologies in the Post-Newtonian Approximation [PDF]

open access: yes, 2000
In this paper we explore how far the post-Newtonian theory goes in overcoming the difficulties associated with anisotropic homogeneous cosmologies in the Newtonian approximation.

Investigation of second grade viscoelastic non-Newtonian nanofluid flow on the curve stretching surface in presence of MHD

open access: yesResults in Engineering, 2023
MHD extended flow of second-grade viscoelastic nanofluid is studied in two-dimensional mode on a curve stretching surface. Items like Joule heating and curvature parameter have been applied to inspect the heat transfer and mass transfer rates. To produce

Ultrasonic Characterization of Newtonian and Non-newtonian Fluids [PDF]

open access: yesUniversal Journal of Physics and Application, 2018
Viscous liquid causes a loss of acoustic energy for acoustic wave propagation through the liquid. From an acoustical point of view, Glycerin being Newtonian is a more complex medium as it is heterogeneous, anisotropic and viscoelastic. Non-Newtonian liquids like PEG-SiO2, DMF-SiO2 solutions show shear-dependent nonlinear Viscosity.
