Significance of radiative heat transfer analysis for magnetized Eyring Powell fluid comprising moment of tiny ferromagnetic nanoparticles and viscous dissipation

摘要

Nanotechnology appeal to a significant consideration due to its environmental friendliness as well as variety of applications in field of medicine, treatment of cancer, nano-robot, bio-nano size devices, aircraft engineering, distillation of water etc. Basic aim behind this inspection is scrutinizing the efficacy of radiative aspect in magnetized Eyring Powell nanofluid configured by impervious surface. The determination of present research work is to explore the 2-D fluid flow of Eyring Powell ferrofluid with effects of a reasonable magnetic field called magnetic dipole. Individualities and important properties of viscous dissipation factor as well as thermophoresis parameter for Eyring Powell model of ferrofluid detaining the important features of temperature gradient are under consideration too. The coupled systems of PDEs are transformed into set of ODEs. Moreover, bvp4c scheme is used to tackle these ODEs. Impacts of some physical parameters are also addressed and shown graphically. It is perceived that temperature increases for thermophoresis, at the same time as decay when we increase in Prandtl number. The Concentration profile of ferrofluid shows declining behavior when we increase the values for parameter of Brownian motion along with Schmidt number. The elaborated physical quantity named Nusselt number is evaluated numerically and presented in tabular form. Here bvp4c technique is used for solving the problem which is a numeric solution of reduced coupled nonlinear set of equations, after that it is explained with help of graphs.
