Couple on a rotating permeable sphere in a couple stress fluid
Ain Shams Engineering Journal, 2018 In this paper, the flow generated by the slow steady rotation of a permeable sphere with thin surface about its axis of symmetry in an incompressible couple stress fluid which is otherwise at rest is studied.

Off-Centered Stagnation Point Flow of a Couple Stress Fluid towards a Rotating Disk [PDF]
The Scientific World Journal, 2014 An investigation has been made to study the off-centered stagnation flow of a couple stress fluid over a rotating disk. The model developed for the governing problem in the form of partial differential equations has been converted to ordinary ...

Drag on a slip spherical particle moving in a couple stress fluid
Alexandria Engineering Journal, 2016 The creeping motion of a rigid slip sphere in an unbounded couple stress fluid is investigated. The linear slip boundary condition and the vanishing couple stress condition are applied on the surface of the sphere.

On Onset of Chaotic Convection in Couple-Stress Fluids
Mathematical Modelling and Analysis, 2014 The effect of couple-stress fluid field on chaotic convection in a fluid layer heated from below was studied in this paper based on the theory of dynamical systems. A low-dimensional, Lorenz-like model was obtained using Galerkin truncated approximations.
