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 ...

Cilia-assisted hydromagnetic pumping of biorheological couple stress fluids [PDF]
Propulsion and Power Research, 2019 A theoretical study is conducted for magnetohydrodynamic pumping of electro-conductive couple stress physiological liquids (e.g. blood) through a two-dimensional ciliated channel. A geometric model is employed for the cilia which are distributed at equal

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.

Non-Stationary Helical Flows for Incompressible Couple Stress Fluid
Mathematics, 2023 We explored here the case of three-dimensional non-stationary flows of helical type for the incompressible couple stress fluid with given Bernoulli-function in the whole space (the Cauchy problem).

Stokes' Problems for an Incompressible Couple Stress Fluid
Nonlinear Analysis, 2008 Stokes’ first and second problems for an incompressible couple stress fluid are considered under isothermal conditions. The problems are solved through the use of Laplace transform technique.

Journal of Applied Mathematics, 2022 In this paper, we study the flow of two immiscible fluids namely, couple stress fluid and Jeffrey fluid in a porous channel. Instead of the classical no-slip conditions on the boundaries, we used slip boundary conditions, which are more realistic and ...

Couple stress fluid past a sphere embedded in a porous medium [PDF]
Archive of Mechanical Engineering, 2021 This paper concerns the analytical investigation of the axisymmetric and steady flow of incompressible couple stress fluid through a rigid sphere embedded in a porous medium. In the porous region, the flow field is governed by Brinkman's equation.

Couple stress fluid flow due to slow steady oscillations of a permeable sphere
Nonlinear Engineering, 2020 The study of oscillating flow of a Couple Stress fluid past a permeable sphere is considered. Analytical solution for the flow field in terms of stream function is obtained using modified Bessel functions.
