Abstract The electroosmotic flow of non-Newtonian fluid–Eyring fluid in microparallel pipes under high zeta potential driven by the combination pressure and electric force is studied. Without using Debye–Hückel (DH) linear approximation, numerical solutions distribution velocity obtained finite difference method are compared with analytical approximate DH approximation. results show that this a...

The thermal management of a system needs an accurate and efficient measurement exergy. For optimal performance, entropy should be minimized. This study explores the enhancement exchange in stream Eyring–Powell fluid comprising nanoparticles saturating vertical oriented dual cylindrical domain with uniform conductivity viscous dissipation effects. A symmetrical sine wave over walls is used to in...

This article examines the effects of homogeneous-heterogeneous reactions and Newtonian heating in magnetohydrodynamic (MHD) flow of Powell-Eyring fluid by a stretching cylinder. The nonlinear partial differential equations of momentum, energy and concentration are reduced to the nonlinear ordinary differential equations. Convergent solutions of momentum, energy and reaction equations are develo...

The main theme of this paper is the modelling error associated with the choice of constitutive equations and associated parameter sensitivity. These key concepts are rst discussed in a general way and explored in detail subsequently for three ow application problems which share certain similarities not only in the nite element formulation but also in the nature of the non-linear constitutive la...

In this paper the MHD of a Non-Newtonian unsteady flow of an incompressible fluid under the effect of couple stresses and a uniform external magnetic field is analysed by using the Eyring Powell model. In the first approximation the solution is obtained by using the Mathematica computational program with assuming a pulsatile pressure gradient in the direction of the motion. In the second order ...

This article explores the influence of polymers on boundary layer flow, heat transfer, and mass transfer control non-Newtonian-based nanofluids flowing past a stretching surface. The mathematical model incorporates Oldroyd-B to analyze effects polymers, while Powell–Eyring Reiner–Philippoff viscosity models are employed study behavior non-Newtonian fluids. dispersion is adopted account for nano...

In the current study, since nanofluids have a high thermal resistance, and because non-Newtonian (Ree-Eyring) fluid movement on stretching sheet by means of suspended nanoparticles AA7072-AA7075 is used, proposed mathematical model takes into account influence magnetic dipoles Koo-Kleinstreuer model. The Cattaneo-Christov used to calculate heat transfer in two-dimensional flow Ree-Eyring nanofl...
