Electro-magnetohydrodynamic flow and heat transfer of a third-grade fluid using a Darcy-Brinkman-Forchheimer model

Abstract

Purpose The purpose of this paper is to examine the electro-magnetohydrodynamic behavior of a third-grade non-Newtonian fluid, flowing between a pair of parallel plates in the presence of electric and magnetic fields. The flow medium between the plates is porous. The effects of Joule heating and viscous energy dissipation are studied in the present study. Design/methodology/approach A semi-analytical/numerical method, the differential transform method, is used to obtain solutions for the system of the nonlinear differential governing equations. This solution technique is efficient and may be adapted to solve a variety of nonlinear problems in simple geometries, as it was confirmed by comparisons between the results using this method and those of a fully numerical scheme. Findings The results of the computations show that the Darcy–Brinkman–Forchheimer parameter and the third-grade fluid model parameter retards, whereas both parameters have an inverse effect on the temperature profile because the viscous dissipation increases. The presence of the magnetic field also enhances the temperature profile between the two plates but retards the velocity profile because it generates the opposing Lorenz force. A graphical comparison with previously published results is also presented as a special case of this study. Originality/value The obtained results are new and presented for the first time in the literature.

Impact of Soret and Dufour on bioconvective flow of nanofluid in porous square cavity

“…The gravitational vector g acts in the negative direction of the y ‐axis. Equations of suspension holding oxytactic microorganisms rely on the formulation of Hillesdon and Pedley 7 . A dilute solution is presumed and terms of inertia are disregarded owing to extreme slow movement of bioconvection.…”

“…The impact of nanoparticles (Cu, Al 2 O 3 , TiO 2 , SiO 2 , etc.) on heat transfer in porous media containing nanofluids is examined in the studies of Tiwari and Das, 4 Allguvelli et al, 5 and Rout et al 6 Zhang et al 7 studied the flow and heat transfer in the porous medium of the Forchheimer model. Bhatti and Abdelsalam 8 studied the entropy generation in a Darcy porous channel with the effects of partial slip on a magnetic dusty liquid.…”

Comprehensive study of thermophoretic diffusion deposition velocity effect on heat and mass transfer of ferromagnetic fluid flow along a stretching cylinder

“…Further, he explained the consequences of non-Fourier heat flux on the heat transfer of viscoelastic liquid. Now a days, several researchers are using different numerical and analytical tools to study the flow and heat transfer behavior of different fluid flow patterns [29][30][31][32][33] in which Runge-Kutta-Fehlberg's fourthfifth order technique (RKF-45) [34][35][36][37] is one of the utmost significant numerical simulation tool with the high calculational speed and slight cost. Moreover, related to the high calculational speed, broad info in more details like fluctuations in thermal, concentration and velocity can be attained through the contemplated domains.…”

Thermal characteristics of forced convection in combined pressure and shear‐driven flow of a non‐Newtonian third‐grade fluid through parallel plates

“…30 The governing equations are solved by Adomian Decomposition Method (ADM) and the buoyancy force and internal force are observed to enhance the rate of heat transfer. EMHD heat transport in the porous third-grade fluid was examined by Zhang et al 31 Effects of viscous dissipation and Joule heating were included in the analysis. The governing equations were solved employing ADM and it was observed that the velocity decreases with an incline in the Darcy-Brinkman-Forchheimer parameter and the third-grade fluid parameter.…”
