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.
