Similarity solutions for unsteady shear-stress-driven flow of Newtonian and power-law fluids : slender rivulets and dry patches [PDF]

open access: yes, 2011
Unsteady flow of a thin film of a Newtonian fluid or a non-Newtonian power-law fluid with power-law index N driven by a constant shear stress applied at the free surface, on a plane inclined at an angle α to the horizontal, is considered.

The shear-driven Rayleigh problem for generalised Newtonian fluids [PDF]

open access: yes, 2014
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

A mathematical model of fluid flow in a scraped-surface heat exchanger [PDF]

open access: yes, 2007
A simple mathematical model of fluid flow in a common type of scraped-surface heat exchanger in which the gaps between the blades and the device walls are narrow, so that a lubrication-theory description of the flow is valid, is presented.

Steady flow of power-law fluids in a 1:3 planar sudden expansion [PDF]

open access: yes, 2013
The laminar flow of inelastic non-Newtonian fluids, obeying the power-law model, through a planar sudden expansion with a 1:3 expansion ratio was investigated numerically using a finite volume method. A broad range of power-law indices in the range 0.2 n

Wall effects on the transportation of a cylindrical particle in power-law fluids [PDF]

open access: yes, 2011
The present work deals with the numerical calculation of the Stokes-type drag undergone by a cylindrical particle perpendicularly to its axis in a power-law fluid.

Modeling of the vane test using a power-law fluid and model order reduction techniques: application to the identification of cement paste properties

open access: yesComptes Rendus. Mécanique, 2021
The effective modeling of fresh cementitious materials during setting is an active and challenging research topic. The material behavior as well as the parameters and properties are not fully understood yet.

Drilling fluid loss model and loss dynamic behavior in fractured formations

open access: yesPetroleum Exploration and Development, 2014
In view of the lost circulation in fractured formations, a two-dimensional transient model for describing a power-law drilling fluid loss in an arbitrarily-oriented, compressible, permeable, rough-walled fracture was introduced.

Slow motion of a sphere towards a plane through confined non-Newtonian fluid [PDF]

open access: yes, 2011
The time needed for the contact of two spheres or a sphere with a rigid plane is mainly controlled by the hydrodynamic drainage of the film located in the gap as long as its thickness is out of range of the Van der Waals interactions.

Transient Two-Layer Electroosmotic Flow and Heat Transfer of Power-Law Nanofluids in a Microchannel

open access: yesMicromachines, 2022
To achieve the optimum use and efficient thermal management of two-layer electroosmosis pumping systems in microdevices, this paper studies the transient hydrodynamical features in two-layer electroosmotic flow of power-law nanofluids in a slit ...
