Numerical Computation of Extrusion and Draw-extrusion Cable-coating Flows with Polymer Melts

open access: yesApplied Rheology, 2014
This paper is concerned with the numerical solution of polymer melt flows of both extrudate-swell and tube-tooling die-extrusion coatings, using a hybrid finite element/finite volume discretisation fe/fv.

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.

Particle Focusing in a Straight Microchannel with Non-Rectangular Cross-Section

open access: yesMicromachines, 2022
Recently, studies on particle behavior under Newtonian and non-Newtonian fluids in microchannel have attracted considerable attention because particles and cells of interest can be manipulated and separated from biological samples without any external ...

Cattaneo–Christov theory for a time-dependent magnetohydrodynamic Maxwell fluid flow through a stretching cylinder

open access: yesAdvances in Mechanical Engineering, 2021
This research work explores the thermal and mass transport phenomena for a time-dependent Maxwell fluid flow in the presence of Cattaneo–Christov concept. The Maxwell fluid flow is analyzed through a stretching cylinder and sheet.

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

High performance microfluidic rectifiers for viscoelastic fluid flow [PDF]

open access: yes, 2012
The flow of Newtonian and non-Newtonian fluids within microfluidic rectifiers with a hyperbolic shape was investigated to assess the effect of the bounding walls on the diodicity of the microfluidic device and achieve high flow anisotropy.

New analytical equations for productivity estimation of the cyclic CO2-assisted steam stimulation process considering the non-Newtonian percolation characteristics

open access: yesJournal of Petroleum Exploration and Production Technology, 2018
The research course in the estimation of productivity of cyclic steam stimulation wells can be divided into three stages: (a) the mobility of heavy oil in the cold area is neglected, (b) the mobility of heavy oil in the cold area is considered—however ...

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 ) .
