The Spreading of Power-Law Fluids

2001
A thin-film formulation for the capillary-driven spreading of a power-law fluid is analysed to clarify, in particular, the relationship between macroscopic and microscopic contact angles and the dynamics of spreading in the completely-wetting case. The Newtonian fluid emerges as a critical case within the one-parameter family of evolution equations ...

Blade coating of a power-law fluid

Physics of Fluids, 1999
In this paper we re-examine the problem of applying a thin layer of a power-law fluid to a solid substrate by means of a simple blade coater. Specifically we use lubrication theory to examine steady plane flow of a power-law fluid in the narrow nonuniform channel formed between a fixed blade of prescribed shape and a plane substrate moving parallel to ...

Entrance effects for power‐law fluid

Polymer Engineering & Science, 1994
AbstractEntrance pressure losses for the creeping flow of a power‐law fluid are calculated for an abrupt contraction of ratio 2, 4, 8 and ∞ for both the axisymmetric and planar cases using P2P1 and PP1 finite elements. Contrary to some earlier findings in the literature, the entrance pressure loss obtained by using the two different types of finite ...

The drag on a sphere in a power-law fluid

Journal of Non-Newtonian Fluid Mechanics, 1985
Using a finite-element program, the drag on an unbounded fluid in an (inelastic) power-law fluid is estimated. Comparison with upper and lower bounds, and with experimental data is given. Some remarks on wall effects are also made, and it is shown that wall effects are negligible for \(n\leq 0.5\).

Turbulent Flow of Power-Law Fluids

Journal of the Hydraulics Division, 1975
Velocity profiles for the steady incompressible turbulent flow of power-law fluids through circular conduits were calculated by numerical quadrature considering both the viscous stresses and the Reynolds' stresses operative over the entire cross section of the flow. A non-Newtonian stress coeffiecient, K sub Sn, was introduced along with mixing length,

Natural convection in power-law fluids

International 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 ...

Peristaltic Transport of Two-Layered Power-Law Fluids

Journal 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.

Decay of turbulence in a power-law fluid

The Physics of Fluids, 1985
The final stages of decay of isotropic homogeneous turbulence are studied in a generalized Newtonian fluid, with a viscosity that depends on the mean rate of energy dissipation. The analysis is similar to that for Newtonian fluids. For a power-law fluid with power-law index n, the turbulent kinetic energy varies with time t as t−10/(7n−3), agreeing ...

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.
