Peristaltic transport of a couple-stress fluid
Rheologica Acta, 1986The problem of peristaltic transport of a couple-stress fluid has been investigated under a zero Reynolds number and long wavelength approximation. A comparison of the results with those for a Newtonian fluid model shows that the magnitude of the pressure rise under a given set of conditions is greater in the case of the couple-stress fluid.

On Diffusion of Vorticity in Couple Stress Fluid
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1988The objective of the present paper is to examine the influence of polar effects on the diffusion of vorticity in couple stress fluids represented by Stokes' constitutive equations. In particular, the diffusion of a line vortex filament, the flow in a double array of vortices and the flow in the wake behind a two-dimensional grid are studied.

Couple-Stress in Peristaltic Transport of a Magneto-Fluid
Physica Scripta, 2001Summary: Peristaltic pumping by a sinusoidal travelling wave in the wall of a two-dimensional channel filled with a viscous incompressible couple-stress of a magneto-fluid is investigated theoretically and graphically. A perturbation solution is obtained which satisfies the momentum equation for the case in which the amplitude ratio is small.

Couple-stresses in peristaltic transport of fluids
Journal of Physics D: Applied Physics, 1994Summary: Peristaltic pumping by a sinusoidal traveling wave in the walls of a two- dimensional channel field with a viscous incompressible couple-stress fluid is investigated. A perturbation solution is obtained which satisfies the momentum equation for the case in which the amplitude ratio (wave amplitude/channel half width) is small. The results show

The Physics of Fluids, 1966
The effects of couple stresses in fluids are considered. Linearized constitutive equations are proposed for force and couple stresses. A series of boundary-value problems are solved to indicate the effects of couple stresses as well as for experiments measuring the various material constants. It is found that a size effect comes in which is not present

Dynamics of a Couple‐Stress Fluid Membrane
Studies in Applied Mathematics, 1984This work concerns the dynamics of a two‐dimensional (surface) fluid membrane which resists bending in a manner reminiscent of elastic shells. Such bending stiffness can arise from the molecular structure of the membrane, the molecules being treated as “directors” oriented normal to the surface.

A Uniqueness Theorem on Couple-Stress Theory of Fluids
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1983Existence and uniqueness of solution for the three-dimensional exterior problem is established by first proving a reciprocal theorem which is then used to obtain an integral representation for the velocity vector in terms of fundamental solutions for both bounded and unbounded domains. This representation then yields the uniqueness.
