Abstract

The non-Newtonian Sutterby fluid model can be implied to characterize the significant characteristics of shear-thinning and shear-thickening for various ranges of the power-law index. The Sutterby fluid has a vast number of applications in engineering processes and industrial fluid mechanics. The steady two-dimensional stagnant flow of Sutterby nanofluid inside the boundary layer over a stretching wedge placed in a porous medium is investigated. The viscous incompressible fluid is electrically conducting, and a uniform magnetic field is imposed perpendicularly. The heat and mass transfer phenomenon is analyzed by incorporating the effects of nonlinear radiation, viscous dissipation, Joule heating, heat source/sink, and activation energy subject to convective-Nield boundary conditions. The physically modeled partial differential equations (PDEs) are lessened into ordinary differential equations (ODEs) with precise similarity variables. The numerical solution is obtained through the shooting method. The effects of several types of emerging parameters upon the dimensionless distributions of velocity, temperature, and concentration are exhibited graphically. A tabular comparison is presented to show the convergence and accuracy of the shooting method. It can be concluded that the pertinent parameters are altered in such a way that they have produced a substantial influence upon the dimensionless boundary layer distributions. The fluid velocity enhances, whereas temperature and concentration of nanofluid are observing two diverse behaviors for the pertinent parameters. Finally, the present study effectively fills the missing gap in the existing literature.
