Effects of chemical reaction, Soret and Dufour parameters on MHD dissipative Williamson nanofluid flow over a slippery stretching sheet through a porous medium

Abstract

ABSTRACT The goal of this study is to determine the effects of Soret, Dufour, and chemical reaction parameters on 2-D MHD Williamson nanofluid flow over a slippery-stretching sheet immersed in a porous medium. Under the influence of both magnetic field and thermal radiation, the significance of viscous dissipation and velocity slip boundary condition with heat generation have been explored. Similarity components were used to turn the nonlinear Partial Differential Equations (PDEs) into nonlinear Ordinary Differential Equations (ODEs), and they were solved using the fourth-order approach of the Runge–Kutta (R–K) method along with the shooting technique. The numerical computations were subsequently illustrated visually to demonstrate the influence of various physical factors on the plots of temperature, velocity, and concentration of the nanofluid. With the use of comparison with previously published data in a restricted sense, the veracity of computation results is evaluated. The tabular values illuminate that the local skin friction coefficient upsurge as the values of the magnetic parameter, porosity parameter, and Brownian motion parameter intensifies, whereas the opposite trend exists for other parameters. The local Nusselt number grows as the Schmidt number rises whereas the reverse trend was experienced for the freed-up parameters.
