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

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.

A general expression is derived for the drag experienced by an axially symmetric body in the slow steady flow of Stokes' couple stress fluids. The result is compared with that obtained for micropolar fluids and then applied to the particular case of flow past a sphere.

Linear and weakly nonlinear triple diffusive convection in a couple stress fluid layer [PDF]
International Journal of Heat and Mass Transfer, 2014 The effect of couple stresses on linear and weakly nonlinear stability of a triply diffusive fluid layer is investigated. Several departures not observed either in singly or doubly diffusive couple stress fluid layer have been identified while analyzing ...

Integral Representations in Couple Stress Theory of Fluids
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1979AbstractThe system of differential equations characterizing the slow, steady, incompressible flow of couple stress fluids is examined. Integral representation for the velocity vector is obtained with the aid of a constructed fundamental singular solution and a derived reciprocity theorem.

Peristaltic flow of a couple stress fluid in an asymmetric channel
Biorheology: The Official Journal of the International Society of Biorheology, 2007This paper presents an analysis of the peristaltic flow of a couple stress fluid in an asymmetric channel. The asymmetric nature of the flow is introduced through the peristaltic waves of different amplitudes and phases on the channel walls. Mathematical modelling corresponding to a two-dimensional flow has been carried out.

Slider bearings lubricated by fluids with couple stress
Wear, 1979Abstract A theoretical study is presented of infinitely long slider bearings assuming the lubricant to be an incompressible fluid with couple stress. Analytical expressions for the load capacity, frictional force and the centre of pressure are derived.

On the Rotation of an Axially Symmetric Body in Couple Stress Fluids
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1984AbstractThe Stokes' flow due to the rotation of an axially symmetric body in couple stress fluids is examined. General solutions are obtained and with the aid of a concentrated point couple, a simple formula for the couple experienced by the body is derived in terms of the angular velocity of the flow field.
