Nonlinear Reynolds equations for non-Newtonian thin-film fluid flows over a rough boundary [PDF]

open access: green, 2018
We consider a non-Newtonian fluid flow in a thin domain with thickness ηε and an oscillating top boundary of period ε. The flow is described by the 3D incompressible Navier-Stokes system with a nonlinear viscosity, being a power of the shear rate (power ...

Convective Nonlinearity in Non-Newtonian Fluids [PDF]

open access: yesPhysical Review Letters, 2000
In the limit of infinite yield time for stresses, the hydrodynamic equations for viscoelastic, Non-Newtonian liquids such as polymer melts must reduce to that for solids. This piece of information suffices to uniquely determine the nonlinear convective derivative, an ongoing point of contention in the rheology literature.

Comments on the paper “Nonlinear Convective Flow of Maxwell ‎Fluid over a Slendering Stretching Sheet with Heat Source/Sink, ‎Mocherla Gayatri, Konda Jayaramireddy, Macherla Jayachandra ‎Babu, J. Appl. Comput. Mech., 8(1), 2022, 60-70”‎ [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2022
Exact solutions for non-Newtonian fluids are rare, particularly for Maxwell fluids [1], such solutions do not exist. Generally, in non-Newtonian fluids, the relation which connects shear stress and shear rate is non-linear and the constitutive relation ...

Micro Electro-Osmotic Thrusters of Power-Law Fluids for Space Propulsion

open access: yesMicromachines, 2023
In this article, electro-osmotic thrusters (EOTs), which are full of non-Newtonian power-law fluids with a flow behavior index n of the effective viscosity, are theoretically investigated in a microchannel.

Validation of a magneto- and ferro-hydrodynamic model for non-isothermal flows in conjunction with Newtonian and non-Newtonian fluids [PDF]

open access: yes, 2016
This work focuses on the validation of a magnetohydrodynamic (MHD) and ferrohydrodynamic (FHD) model for non-isothermal flows in conjunction with Newtonian and non- Newtonian fluids.
