Influence of non-uniform heat source sink and inclined magnetic field on double-diffusive stagnation point flow of Eyring – Powell nanofluid on a slender stretching sheet

Abstract

In this study, the effect of an inclined magnetic field and a non-uniform heat source sink on a double diffusive convective stagnation point flow in a slender stretching sheet is studied. The suitable similarity transformations are utilized for the conversion of nonlinear differential equations. These converted equations are solved by means of Differential Transformation method (DTM) with the support of symbolic software Mathematica. Further, the effects of appropriate parameter on velocity profile, solute, nanoparticle concentration and temperature profiles are shown graphically with some suitable discussion. It is found that velocity decreases with a rise of magnetic parameter and also non-uniform heat source sink enhances the thermal profile of the system. But, opposite behaviour can be seen in solute concentration and nanoparticle concentration profiles.Such results can be useful in design and structure of materials,where implementation of variable thickness decreases the weight of stretched element and boosts the usage of materials.

Bioconvective Flow of Eyring-Powell Nanofluid Over an Exponentially Sheet

“…Alghamdi et al, [28] studied the magnetohydrodynamic (MHD) movement of a Powell-Eyring tiny fluid over a stretched surface heated convectively. Mali [29] studied the effects of a non-uniform heat source sink and an angled magnetic field on the flow of an Eyring-Powell nanofluid at its double-diffusive stagnation point on a thin stretched sheet. Mishra et al, [30] studied the analysis of the entropy generated by a heat source/sink over a stretching sheet of magnetohydrodynamic Eyring-Powell nanofluid.…”
