On the boundary–layer equations for power–law fluids

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2004
Summary: We reconsider the problem of the boundary-layer flow of a non-Newtonian fluid whose constitutive law is given by the classical Ostwald-de Waele power-law model. The boundary-layer equations are solved in similarity form. The resulting similarity solutions for shear-thickening fluids are shown to have a finite-width crisis resulting in the ...

Natural convection in power-law fluids

open access: yesInternational Communications in Heat and Mass Transfer, 1986
Abstract In the case of natural convection to power-law fluids of high Prandtl number it is shown that the appropriate dimensionless parameters are the generalized Rayleigh number and the power-law index n. Such a presentation brings out more clearly the influence of n on the Nusselt number and facilitates comparison of experimental and analytical ...

Electrokinetically modulated peristaltic transport of power-law fluids.

Microvascular Research, 2016
The electrokinetically modulated peristaltic transport of power-law fluids through a narrow confinement in the form of a deformable tube is investigated. The fluid is considered to be divided into two regions - a non-Newtonian core region (described by the power-law behavior) which is surrounded by a thin wall-adhering layer of Newtonian fluid.

Peristaltic Transport of Two-Layered Power-Law Fluids

open access: yesJournal of Biomechanical Engineering, 1997
Peristaltic transport of two-layered power-law fluids in axisymmetric tubes is studied. Use of the power-law fluid model permits independent choice of shear thinning, shear thickening, or Newtonian fluids for the core and the peripheral layer. The interface between the two layers is determined from a transcendental equation in the core radius.

Helical flow of power‐law fluids

AIChE Journal, 1990
A numerical solution is presented for the helical flow of a power-law fluid between coaxial cylinders. The solution is valid for isothermal steady creeping flow in an annular space of arbitrary thickness. Results are presented in the form of relations between dimensionless integral flow characteristics (e.g.

Spreading dynamics of power-law fluid droplets

Journal of Physics: Condensed Matter, 2009
This paper aims at providing a summary of the theoretical models available for non-Newtonian fluid spreading dynamics. Experimental findings and model predictions for a Newtonian fluid spreading test are briefly reviewed. Then how the complete wetting and partial wetting power-law fluids spread over a solid substrate is examined. The possible extension
