The absence of characteristic material length in the Navier-Stokes equations has led to the development of different couple stress theories. In the present study, for the first time, the relations of a couple stress theory are extended to power-law ...

Transition from dripping to jetting in power-law fluids
This computational study employs a finite volume method with axisymmetric coordinates and volume-of-fluid interface tracking to investigate the regime transition mechanisms from discrete droplet generation to continuous jet breakup in power-law fluid ...

Determination of Rheological Parameters from Measurements on a Viscometer with Coaxial Cylinders
The paper deals with measurements of non-Newtonian fluids on a viscometer with coaxial cylinders. The procedure for determining the rheological model parameters is recommended for power-law fluids and Bingham plastics.

Filtration law for power-law fluids in anisotropic porous media
International audiencehis work is concerned with modelling steady-state slow flow of incompressible power-law fluids in porous media. The macroscopic filtration law is derived by upscaling the pore–scale description. The upscaling technique in use is the

Semi-Analytical Modelling of Evaporating Power-Law Thin Films in Inclined Micro-Channels
The evaporation of a thin liquid film representative of power-law rheology flowing along an inclined channel wall under the combined influence of gravity and surface tension is investigated using a semi-analytical modelling framework.

Simulation of Lubricated Squeezing Flow of a Herschel-Bulkley Fluid Under Constant Force
Lubricated squeezing flow (LSF) of a Herschel-Bulkley fluid between parallel disks under constant force was theoretically analyzed. An analytical expression for the fluid thickness as a function of time was obtained in terms of a hypergeometric function.
