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.

Convection in Couple-Stress Magneto-Fluid
IOSR Journal of Mathematics, 2016 Double-diffusive convection in a couple-stress fluid in the presence of uniform vertical magnetic field through porous medium using linearized stability theory and normal mode analysis is studied. For the case of stationary convection, the stable solute gradient, magnetic field and couple-stress are found to have stabilizing effects whereas medium ...

Stability Analysis in Couple-Stress Rotatory Fluid
WSEAS TRANSACTIONS ON HEAT AND MASS TRANSFER, 2021 The aim of the present research was to study the effect of uniform rotation on the layer of a couple-stress fluid heated from below in porous medium. Following the linearized stability theory, Boussinesq approximation and normal mode analysis, the dispersion relation is obtained.
