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

Numerical Simulation of Gas-Liquid Flow in a Bubble Column by Intermittent Aeration in Newtonian Liquid/Non-Newtonian Liquid

open access: yesInternational Journal of Chemical Engineering, 2018
The dynamic behaviors of gas-liquid two-phase flow were simulated in a lab-scale intermittent bubble column by Euler-Euler two-fluid model coupled with the PBM (population balance model) using two different liquid phases, i.e., Newtonian fluid (water ...

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 ...

Rheology of waxy oils: A critical review

open access: yesApplications in Engineering Science
Waxy oil is a rheologically complex material presenting shear-rate-dependent viscosity, static and dynamic yield stresses, gel elasto-viscoplasticity, time/deformation-dependent gel structure, and irreversibility.

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.

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 ...

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 ) .

On some geometric features of the Kramer interior solution for a rotating perfect fluid [PDF]

open access: yes, 1999
Geometric features (including convexity properties) of an exact interior gravitational field due to a self-gravitating axisymmetric body of perfect fluid in stationary, rigid rotation are studied.
