Turbulent Flow of Power-Law Fluids
Journal of the Hydraulics Division, 1975Velocity 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, 1986Abstract 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 ...

Decay of turbulence in a power-law fluid
The Physics of Fluids, 1985The 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, 2016The 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.

Withdrawal of power law fluid films
Chemical Engineering Science, 1970Abstract The thickness of a layer of a power law fluid on a sheet, which is withdrawn from a bath, is determined for the three regimes of withdrawal conditions. The flux in viscous withdrawal is, like for a newtonian liquid, lower than the maximum possible flux on a sheet moving upwards with a certain velocity.

Peristaltic Transport of Two-Layered Power-Law Fluids
Journal of Biomechanical Engineering, 1997Peristaltic 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.

Interfacial pattern formation in confined power-law fluids
Physical Review E, 2014The interfacial pattern formation problem in an injection-driven radial Hele-Shaw flow is studied for the situation in which a Newtonian fluid of negligible viscosity displaces a viscous non-Newtonian power-law fluid. By utilizing a Darcy-law-like formulation, we tackle the fluid-fluid interface evolution problem perturbatively, and we derive second ...

Peristaltic Transport of a Power-Law Fluid With Variable Consistency
Journal of Biomechanical Engineering, 1982Effects of the consistency variation on the peristaltic transport of a non-Newtonian power-law fluid fluid through a tube have been investigated by taking into account the existence of a peripheral layer. It is shown that the flow rate flux, for zero pressure drop, increases as the amplitude of the peristaltic wave increases but it decreases due to the

On the flow of power-law fluids
2011An update on generalized similarity transformation applied to the flow of power-law fluids is presented. The paper surveys both steady and unsteady flow problems: (i) wall jets and (ii) unsteady liquid-film stretching. The latter case assumes that the flow field is similar in time and space. Some practical issues are addressed.
