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 ...

Unsteady Helical Flows of a Size-Dependent Couple-Stress Fluid [PDF]
Advances in Mathematical Physics, 2017 The helical flows of couple-stress fluids in a straight circular cylinder are studied in the framework of the newly developed, fully determinate linear couple-stress theory.

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.

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 ...

Fluid-Solid Coupling Simulation of Wall Fluid Shear Stress on Cells under Gradient Fluid Flow [PDF]
Applied Bionics and Biomechanics, 2021 Fluid shear stress (FSS) plays a crucial role for cell migration within bone cavities filled with interstitial fluid. Whether the local wall FSS distribution on cell surface depends on the global gradient FSS of flow field should be clarified to explain our previous experimental observation.

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.
