A rigorous formulation of the cosmological Newtonian limit without averaging

open access: yes, 2010
We prove the existence of a large class of one-parameter families of cosmological solutions to the Einstein-Euler equations that have a Newtonian limit.

Carreau fluid model for blood flow through a tapered artery with a stenosis

open access: yesAin Shams Engineering Journal, 2014
In present article, we have studied the blood flow through tapered artery with stenosis. The non-Newtonian nature of blood in small arteries is analyzed mathematically by considering the blood as Carreau fluid.

The Hydrodynamics of Non-Newtonian Fluids. II [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 1948
In this paper, the general hydrodynamic theory of visco-inelastic, incompressible, non-Newtonian fluids, developed in a previous paper (l), is applied to the problem of the flow of such a fluid through a tube of circular cross-section. It is found that the absolute values of the normal stress components are no longer uniform over a cross-section of the

Force moments of an active particle in a complex fluid

open access: yes, 2017
A generalized reciprocal theorem is formulated for the motion and hydrodynamic force moments of an active particle in an arbitrary background flow of a (weakly nonlinear) complex fluid.

A note on acoustic black holes in neo-Newtonian theory

open access: yes, 2013
Newtonian fluid dynamics allows the construction of acoustic metrics from which black hole configurations can be studied. However, relativistic pressure effects are neglected within Newtonian theory.

Numerical study of shear thickening fluid with discrete particles embedded in a base fluid

open access: yesInternational Journal of Multiphysics, 2016
The Shear Thickening Fluid (STF) is a dilatant material, which displays non-Newtonian characteristics in its unique ability to transit from a low viscosity fluid to a high viscosity fluid.

On a degenerate parabolic equation with Newtonian fluid∼non-Newtonian fluid mixed type

open access: yesJournal of Inequalities and Applications, 2021
We study the existence of weak solutions to a Newtonian fluid∼non-Newtonian fluid mixed-type equation u t = div ( b ( x , t ) | ∇ A ( u ) | p ( x ) − 2 ∇ A ( u ) + α ( x , t ) ∇ A ( u ) ) + f ( u , x , t ) .

THE EFFECTS OF BLOOD REHEOLOGICAL ON THE FLOW THROUGH AN AXISYMMETRIC ARTERIAL STENOSIS

open access: yesJournal of Engineering, 2011
The prediction of the blood flow through an axisymmetric arterial stenosis is one of the most important aspects to be considered during the Atherosclrosis.

The impacts of varying magnetic field and free convection heat transfer on an Eyring–Powell fluid flow with peristalsis: VIM solution

open access: yesJournal of Taibah University for Science, 2020
A mathematical model of a non-Newtonian fluid (Eyring–Powell fluid) flow with peristalsis under the effect of varying magnetic field and free convection heat transfer has been discussed.
