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 ...

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Chemical Engineering Science, 1970Abstract The thickness of a layer of a power law fluid on a sheet, which is withdrawn from a bath, is determined for the three regimes of withdrawal conditions.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

Power-law scattering in fluids with a nonscalar order parameter
Physical Review E, 1993We 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, 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.

Research on sedimentation characteristics of squirmer in a power-law fluid
The European Physical Journal ESedimentation 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, 1996Summary: 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
