Slippery flow of non-Newtonian Maxwell thermal nanofluid past a permeable vertically stretched sheet through a porous medium

This article's primary goal is to use Soret and Dufour impact to control the mixed convective flow and heat transfer of a non-Newtonian Maxwell nanofluid via a vertically slippery stretched sheet through a porous medium. By studying the well-known Buongiorno model, which enables us to highlight attractive features of thermophoretic diffusion and Brownian motion, we can determine the mass and thermal characteristics of a nanofluid. Additionally considered are the effects of varying temperature and concentration on a stretched, linearly permeable surface. The circumstance where the viscosity of a Maxwell nanofluid alters with temperature is the primary focus of the paper. Using the principles of conservation of mass, momentum, and energy, a mathematical model of the present problem is built. The forms of the partial differential equations regulating the mathematical model are converted into the structures of ordinary differential equations via the suitable dimensionless variables. Next, using the shooting method, the resulting equations are numerically resolved. Plots of several emerging relevant parameters versus velocity, temperature, and concentration distributions are made, and the results are presented in accordance with them. It was found that the Soret and Dufour parameters, as well as the slip velocity assumption, had an impact on the processes of heat and mass transfer. The tables presented contain information on the skin friction coefficient, Nusselt number, and Sherwood number, which are linked to the velocity, temperature, and concentration distributions. These tables display various values of the controlling physical emergent parameters.
