Effects of cross diffusion on radiative MHD flow over a rotating cone through porous medium

Abstract

This work examines innovative elements of the impacts of thermal radiation, Soret, and Dufour effects on the magnetohydrodynamic (MHD) flow of viscous liquid past a spinning cone via a porous medium from the perspective of advancements in mass as well as heat transfer. Heat generation/absorption, dissipation, thermal flux as well as Joule heating, and other physical factors are taken into account when expressing the energy equation. The physical characteristics of the first-order chemical process that generates entropy are examined. A boundary value problem with reduced dimensions that was obtained from the governing equations is solved for the system using the bvp4c technique. Graphs are used to show how effective factors affect the concentration, entropy generation rate, temperature, and velocity. Based on our study, tangential velocity, as well as azimuthal velocity, is diminishing visually for greater values of the magnetic as well as porosity parameters, but the behavior of the mixed convection parametric exposes the regress behavior. Additionally, when the Dufour parametric increases, parameters of Soret and chemical reaction both show declining behavior.
