Heat and Mass Transfer of Hydrodynamic Boundary Layer Flow along a Flat Plate with the Influence of Variable Temperature and Viscous Dissipation

Abstract

This paper elucidates heat together with mass transfer through a flat plate and variable temperature as well as dissipative effects. The flow assumptions resulted to steady flow equations which were simplified with appropriate similarity variables. The simplified equations were numerically solved and results are presented both in graphs and tabular form. Effects of physical quantities of interest were presented graphically. The local skin friction is observed to increase because of increase in Schmidt number. Also, increase in Prandtl number is found to boast the local Nusselt number. The behaviour of increase in Prandtl number is found to be unstable within the boundary layer regime while increase in Eckert number produces heat energy within the fluid layers. Finally, the validation of the present problem is done by comparing with previous works and was in perfect agreement.

Mathematical Modeling on Magnetohydrodynamics Upper Convected Maxwell Fluid Flow Past a Flat Plate Using Spectral Relaxation Approach

“…The treatise of Oyelami and Falodun [20], on heat in company with mass transfer of hydrodynamic flow towards a horizontal plate, together with the consequence of altered temperature along with viscous depletion, was a Newtonian fluid together with a variable temperature, also with viscous dissipation and chemical reaction. In their previous study, there was no Cattaneo-Christov model, and the Soret-Dufour mechanism and magnetic field strength were also neglected.…”

“…In their previous study, there was no Cattaneo-Christov model, and the Soret-Dufour mechanism and magnetic field strength were also neglected. The work done by Oyelami and Falodun [20] has been extended in this study to fill the missing gap. The case in this study shall focus on the MHD heat and mass transfer motion of upper convection Maxwell fluid along a flat plate with thermal radiation, variable temperature, the Cattaneo-Christov model, and the Soret-Dufour mechanism.…”

“…The case in this study shall focus on the MHD heat and mass transfer motion of upper convection Maxwell fluid along a flat plate with thermal radiation, variable temperature, the Cattaneo-Christov model, and the Soret-Dufour mechanism. The work done by Oyelami and Falodun [20] was on a Newtonian fluid with variable temperature, viscous dissipation, and chemical reactions. The present study hereby extends their analysis by considering a non-Newtonian fluid moving with the consequences of thermal radiation, magnetic, and Soret-Dufour dynamics.…”

“…Mondal et al, [19] investigated MHD mass transfer when chemically reactive fluid was present. Oyelami and Falodun [20] used spectral relaxation to investigate the chemical reaction impact on non-Newtonian Casson fluid. Idowu & Falodun [21] investigated steady natural convection flow movement with chemical reactions.…”

Double-Diffusive MHD Viscous Fluid Flow in a Porous Medium in the Presence of Cattaneo-Christov Theories

“…There are exceptions to every rule. Many equipment, like the MHD current generator and the Hall accelerator, use magnetohydrodynamic flows to transfer heat and mass, and recent advances in this area have been impressive [1][2][3]. Magnetic field effects on the motion of electrically executing viscous fluid with mass transport are also useful for the study of the planetary atmosphere.…”
