Conjugate transfer of heat and mass in unsteady flow of a micropolar fluid with wall couple stress
AIP Advances, 2015 This is an attempt to investigate the unsteady flow of a micropolar fluid with free convection caused due to temperature and concentration differences. Micropolar fluid is taken over a vertical plate oscillating in its own plane.

Turbulence Intensity Modulation by Micropolar Fluids
Fluids, 2021 Fluid microstructure nature has a direct effect on turbulence enhancement or attenuation. Certain classes of fluids, such as polymers, tend to reduce turbulence intensity, while others, like dense suspensions, present the opposite results.

On a System of Equations of a Non-Newtonian Micropolar Fluid [PDF]
Journal of Applied Mathematics, 2015 We investigate a problem for a model of a non-Newtonian micropolar fluid coupled system. The problem has been considered in a bounded, smooth domain ofR3with Dirichlet boundary conditions. The operator stress tensor is given byτ(e(u))=[(ν+ν0M(|e(u)|2))e(u)].

Theory of Micropolar Fluids [PDF]
Indiana University Mathematics Journal, 1966 Abstract : Equations of motion, constitutive equations and boundary conditions are derived for a class of fluids named micropolar fluids. These fluids respond to micro-rotational motions and spin inertia and therefore can support couple stress and distributed body couples.

Stability analysis of micropolar fluid flow over an exponentially permeable shrinking sheet
, 2020 In the present paper, stability analysis is performed to the dual solutions obtained in boundary layer flow of micropolar fluid over a shrinking sheet with exponential velocity. The problem is first considered as time-dependent problem.

A Regularity Criterion for the Magneto-Micropolar Fluid Equations in B˙∞,∞−1
Discrete Dynamics in Nature and Society, 2013 The paper is dedicated to study of the Cauchy problem for the magneto-micropolar fluid equations in three-dimensional spaces. A new logarithmically improved regularity criterion for the magneto-micropolar fluid equations is established in terms of the ...
