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,

AN ADHESIVE PROBLEM FOR A POWER-LAW FLUID

Chemical Engineering Communications, 2012
The flow caused by the pulling of a circular disk away from a plane rigid surface is investigated when the disk and the surface are separated by a thin layer of power-law fluid of thickness h(t). It is observed that the force exerted by the fluid on the disk is a suction force F, which tends to make the disk adhere to the rigid surface.

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 ...

Interfacial pattern formation in confined power-law fluids

Physical Review E, 2014
The 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 ...

Withdrawal of power law fluid films

Chemical Engineering Science, 1970
Abstract The thickness of a layer of a power law fluid on a sheet, which is withdrawn from a bath, is determined for the three regimes of withdrawal conditions.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.

Power-law scattering in fluids with a nonscalar order parameter

Physical Review E, 1993
We studied the coarsening behavior of two lyotropic liquid-crystal systems by static light scattering. The samples were quenched from the isotropic phase into either the nematic phase or a region of coexistence between nematic and isotropic phases. In the coexistence region, we observed, in both two and three dimensions, Porod power-law tails of the ...

Peristaltic Transport of a Power-Law Fluid With Variable Consistency

Journal of Biomechanical Engineering, 1982
Effects 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

2011
An 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.
