MHD micropolar hybrid nanofluid flow over a flat surface subject to mixed convection and thermal radiation

open access: yesScientific Reports, 2022
Hybrid nanofluids play a significant role in the advancement of thermal characteristics of pure fluids both at experimental and industrial levels. This work explores the mixed convective MHD micropolar hybrid nanofluid flow past a flat surface.

Fundamental solutions for micropolar fluids [PDF]

open access: yesJournal of Engineering Mathematics, 2007
New fundamental solutions for micropolar fluids are derived in explicit form for two- and three-dimensional steady unbounded Stokes and Oseen flows due to a point force and a point couple, including the two-dimensional micropolar Stokeslet, the two- and three-dimensional micropolar Stokes couplet, the three-dimensional micropolar Oseenlet, and the ...

Micropolar Fluid Poro-Elastic Squeeze Film Lubrication between a Cylinder and a Rough Flat Plate — A Special Reference to Synovial Joint Lubrication

open access: yesTribology Online, 2014
In the present paper the effect of micropolar squeeze film lubrication between a cylinder and a poroelastic flat plate is presented. The synovial fluid is modeled as the micropolar fluid and the articular cartilage is considered to be a poroelastic in ...

Theory of Micropolar Fluids [PDF]

open access: yesIndiana 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.

On the local exact controllability of micropolar fluids with few controls [PDF]

open access: yes, 2016
In this paper, we study the local exact controllability to special trajectories of the micropolar fluid systems in dimension d = 2 and d = 3. We show that controllability is possible acting only on one velocity.Comment: 25 pages, accepted for publication

On the Fattorini Criterion for Approximate Controllability and Stabilizability of Parabolic Systems [PDF]

open access: yes, 2014
In this paper, we consider the well-known Fattorini's criterion for approximate controllability of infinite dimensional linear systems of type $y'=A y+Bu$. We precise the result proved by H. O.

Accelerated micropolar fluid--flow past an uniformly rotating circular cylinder

open access: yes, 2016
In this paper, we formulated the non-steady flow due to the uniformly accelerated and rotating circular cylinder from rest in a stationary, viscous, incompressible and micropolar fluid.
