Effects of radiative heat flux and joule heating on electro-osmotically flow of non-Newtonian fluid: Analytical approach

Objective: Many methods have been used to maximize the capacity of heat transport. A constant pressure gradient or the motion of the wall can be used to increase the heat transfer rate and minimize entropy. The main goal of our investigation is to develop a mathematical model of a non-Newtonian fluid bounded within a parallel geometry. Minimization of entropy generation within the system also forms part of our objective. Method: Perturbation theory is applied to the nonlinear complex system of equations to obtain a series solution. The regular perturbation method is used to obtain analytical solutions to the resulting dimensionless nonlinear ordinary differential equations. A numerical scheme (the shooting method) is also used to validate the series solution obtained. Results: The flow and temperature of the fluid are accelerated as functions of the non-Newtonian parameter (via the power-law index). The pressure gradient parameter escalates the heat and volume flux fields. The energy loss due to entropy increases via the viscous heating parameter. A diminishing characteristic is predicted for the wall shear stress that occurs at the bottom plate versus the time-constant parameter. The Reynolds number suppresses the volume flux field.

“…Such type of fluids is categorized as nonlinear or non-Newtonian fluids. 1–4 The non-Newtonian fluids are further classified into three main branches, namely viscoelastic, time-dependent and time-independent. Jeffrey fluid is a famous non-Newtonian fluid that falls into the category of viscoelastic or rate type fluids.…”

Magnetohydrodynamic (MHD) flow of fluids with porous media has several applications in medical and industrial fields, including hyperthermia, wound treatment using magnetic field, cancer treatment, heat exchangers, catalytic reactions and distillation towers. In the present work, we explored the two-phase flow of MHD Jeffrey fluid in the presence of porous media through horizontal walls. The uniform liquid properties and magnetic field effects are also considered in this investigation. The heat and mass transfer effects on fluid flow with the addition of Hafnium metallic particles are evaluated. The governing nonlinear momentum and energy equations are found by using Jeffrey’s stress tensor. We discussed three types of flows, namely, Plane Poiseuille, Plane Couette, and Generalized Couette. The effects of all involved parameters on flow and temperature distributions are deliberated with graphs for all cases separately. The results interpreted that increase in values of Darcy number upsurges the velocity and temperature distributions. Radiation parameter declined the temperature of fluid while Brinkman number enhances temperature in all types of flow. Comparison of Newtonian and non-Newtonian fluid is also presented in this study, and we also validated our results by comparing them with the already existing literature results.

This article addresses the hemodynamic flow of biological fluid through a symmetric channel. Methachronal waves induced by the ciliary motion of motile structures are the main source of Couple stress nanofluid flow. Darcy’s law is incorporated in Navier-Stokes equations to highlight the influence of the porous medium. Thermal transport by the microscopic collision of particles is governed by Fourier’s law while a separate expression is obtained for net diffusion of nanoparticles by using Fick’s law. A closed-form solution is achieved of nonlinear differential equations subject to Newton’s boundary conditions. Moreover, the current findings are compared with previous outcomes for the limiting case and found a complete coherence. Parametric study reveals that nanoflow is resisted by employing Newton’s boundary conditions. Thermal profile enhancement is contributed by the viscous dissipation parameter. Finally, one infers that hemodynamic flow of non-Newtonian fluid is an effective mode of heat and mass transfer especially, in medical sciences for the rapid transport of medicines in drug therapy.
