The shear-driven Rayleigh problem for generalised Newtonian fluids [PDF]
We consider a variant of the classical ‘Rayleigh problem’ (‘Stokes’s first problem’) in which a semi-infinite region of initially quiescent fluid is mobilised by a shear stress applied suddenly to its boundary. We show that self-similar solutions for the

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

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

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

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 ...

High performance microfluidic rectifiers for viscoelastic fluid flow [PDF]
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.

A three-dimensional immersed boundary method for non-Newtonian fluids [PDF]
Fluid-structure-interaction (FSI) phenomenon is common in science and engineering. The fluid involved in an FSI problem may be non-Newtonian such as blood. A popular framework for FSI problems is Peskin's immersed boundary (IB) method.
