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.

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Abstract The thickness of a layer of a power law fluid on a sheet, which is withdrawn from a bath, is determined for the three regimes of withdrawal conditions.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

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.

Research on sedimentation characteristics of squirmer in a power-law fluid

The European Physical Journal E
Sedimentation characteristics of a squirmer in a power-law fluid within a vertical channel are studied numerically using the two-dimensional lattice Boltzmann method. The effects of swimming type (- 5 ≤ β ≤ 5), self-propelling strength (0.5 ≤ α ≤ 1.1), power-law indexes (0.5 ≤ n ≤ 1.5), and the density ratio of the squirmer to the fluid (γ = 1.01, 1.5 ...

On Quasi-static Non=Newtonian Fluids with Power-law

Mathematical Methods in the Applied Sciences, 1996
Summary: We discuss certain classes of quasi-static non-Newtonian fluids for which a power-law of the form \(\sigma^D = \nabla\Phi ({\mathcal E}v)\) holds. Here \(\sigma^D\) is the stress deviator, \(v\) the velocity field, \({\mathcal E} v\) its symmetric derivative and \(\Phi\) is the function \[ \Phi ({\mathcal E}v) = {1\over 2} \mu_\infty|{\mathcal
