Buoyancy Effects on MHD Transport of Nanofluid Over a Stretching Surface With Variable Viscosity

Abstract

In this mathematical study, the time-independent, incompressible, magneto-hydrodynamic nanofluid flow over a vertical stretching surface has been investigated. The impact of gravitational body forces along with convective boundary condition has also been a part of this study. The viscous effects of nanofluid are assumed to be temperature-dependent and in this context, the Reynolds exponential viscosity model has been employed. It is also assumed that the base fluid contains a uniform suspension of nanoparticles. The Buongiorno model comprising the thermophoresis and Brownian motion effects have been taken into account. For the sake of solution, the Runge-Kutta-Fehlberg method has been selected and the resulting outcomes have been compared with the previously published data. Moreover, the graphical plots illustrating the impact of various emerging entities on the momentum, mass, and heat transfer properties have also been provided. It has been noticed that the nanofluid viscosity parameter decelerates the fluid velocity, however, a reversed phenomenon has been achieved for the temperature and the concentration profile. Also, an augmentation in Nusselt number has been noted with the increased thermal and species Grashof numbers.

“…It is examined that the temperature of the fluid is highly affected when the number of dust particles is enhanced. The flow of nanofluid with variable viscosity in attendance of buoyancy effects is examined by Mohsin [27]. The Runge-Kutta-Fehlberg scheme is implemented to achieve a numerical solution to the problem.…”

“…They also examined that the fluid velocity is lowered by enlarging the Weissenberg number. Some more recent remarkable researches featuring MHD may be found at [4][5][6][7] and many therein.…”
