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.

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.

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.

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.

Porous slider bearing with couple stress fluid
Acta Mechanica, 1990Theoretical study of porous slider bearing with couple stress fluid as lubricant is made and the lubrication qualities of couple stress fluid are examined. The lower surface is covered by a thin porous material and the upper one, having arbitrary shape, moves in its own plane with constant velocity.

ROTARY OSCILLATION OF A RIGID SPHERE IN A COUPLE STRESS FLUID
BAU Journal - Science and Technology, 2020In this paper, the rotary oscillation of a rigid sphere in an incompressible couple stress fluid is studied. The classical no slip boundary conditions are imposed on spherical boundary. Moreover, it is assumed that the couple stresses on the boundary of the sphere vanish.

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.

Poiseuille flow of a fluid with couple stress with applications to blood flow
Biorheology, 1969In this paper, the Poiseuille flow of blood is studied. Blood is assumed to be a fluid with couple stress. In order to verify that the rheological properties of blood can be explained in terms of the linear couple stress theory, we compare the velocity profiles of theoretical solutions with the ones obtained experimentally.

An Average Flow Model for Couple Stress Fluids
Tribology Letters, 2003The interactions of surface roughness and flow rheology of couple stress fluids on thin film lubrication problems are modeled. The generalized average Reynolds equation as well as the flow factors is derived. The effects of couple stress parameters (l), the standard derivation of surface roughness (σ i ), the Peklenik
