Micropolar Fluids with Vanishing Viscosity [PDF]

Abstract and Applied Analysis, 2010
A study of the convergence of weak solutions of the nonstationary micropolar fluids, in bounded domains of ℝn, when the viscosities tend to zero, is established. In the limit, a fluid governed by an Euler‐like system is found.

Heat Transfer of Hybrid Nanomaterials Base Maxwell Micropolar Fluid Flow over an Exponentially Stretching Surface

Nanomaterials, 2022
A numerical investigation of three-dimensional hybrid nanomaterial micropolar fluid flow across an exponentially stretched sheet is performed. Recognized similarity transformations are adopted to convert governing equations from PDEs into the set ODEs ...

Applications of modified Darcy law and nonlinear thermal radiation in bioconvection flow of micropolar nanofluid over an off centered rotating disk

, 2021
To improve the heat efficiency base fluids (water, engine oil, glycol), the interaction of nanoparticles (nanotubes, droplets, nanowires, metals and non-metals) into such traditional liquids is the most frequent mechanism and attained the researchers ...

Non-classical continuum theories for solid and fluent continua and some applications

International Journal of Smart and Nano Materials, 2019
This paper presents two specific thermodynamically consistent non-classical continuum theories for solid and fluent continua. The first non-classical continuum theory for solid continua incorporates Jacobian of deformation in its entirety in the ...

Entropy generation analysis and effects of slip conditions on micropolar fluid flow due to a rotating disk

Open Engineering, 2017
This article deals with the investigation of three-dimensional axisymmetric steady flow of micropolar fluid over a rotating disk in a slip-flow regime. Further, the generation of entropy due to heat transfer and fluid friction is identified.

Thermoelastic Plane Waves in Materials with a Microstructure Based on Micropolar Thermoelasticity with Two Temperature and Higher Order Time Derivatives

Mathematics, 2022
The study of the effect of the microstructure is important and is most evident in elastic vibrations of high frequency and short-wave duration. In addition to deformation caused by temperature and acting forces, the theory of micropolar thermoelasticity ...
