Abstract

This article considers the flow, heat and mass transfer of steady, two dimensional, electrically conducting micropolar fluid over a vertically stretching permeable plate in a Darcy Forchheimer porous medium. The study is pivoted on investigating the combined effects of thermo-diffusion (Soret) and diffusion thermo (Dufour) on a thermally radiating and electrically conducting micropolar fluid with the influences of viscous dissipation, heat generation/absorption and chemical reaction of the first order. A uniform magnetic field of magnitude is applied normal to the plate. The governing nonlinear partial differential equations (PDEs) are transformed into a system of coupled nonlinear ordinary differential equations (ODEs) using Lie scaling group of transformations, which are then solved numerically subject to the boundary conditions by Runge-Kutta Fehlberg fourth fifth integration scheme alongside the shooting method. Comparisons are made with the previous studies and an agreement is found between the present study and the previous findings as a special case of the present work. The influences of different flow parameters on the velocity, microrotation, temperature and concentration are discussed and displayed both tabularly and graphically.
