Abstract

Abstract The main objective of this study is to analyze the steady, two dimensional flow of non-Newtonian nanofluid through a porous medium over a stretched sheet. By means of the comparison of other Non-Newtonian liquids Eyring-Powell fluid model have some more advantages because they act as viscous liquids at high shear rates as well. A uniform external magnetic field is applied on the present model. The heat and mass transfer rates are studied in the present study moreover considered non-Newtonian fluid is abiding the Eyring-Powell model. In the energy equation radiation effect is also considered. The problem is mathematically formulated from the flow and there after solved numerically with the help of spectral relaxation method (SRM) along with the mat lab package. There is a significant improvement in the convergence of proposed technique in conjunction with spectral over relaxation (SOR) method. It very well may be noticed that number of iterations are diminished combination with the SOR strategy. Effects of physical parameters of the problem such as, permeability, magnetic in addition to the fluid material parameters like Eckert number, radiation parameter, Prandtl number and Lewis number are analyzed through graphs and tables with some notable applications. The outcomes show that the velocity of the fluid is higher for non-Newtonian nanofluid than the classical nanofluid. An increase in the viscous dissipation and radiation causes increase in the fluid temperature.
