A Mathematical Model of MHD Micropolar Fluid Flow with Thermal-Diffusion and Diffusion-Thermo Effects

Abstract

In this article, we have examined 2-dimensional steady magnetohydrodynamic (MHD) boundary layer flow of viscous micropolar fluid through a stretching surface. Simultaneous effects of thermal-diffusion (Soret) and diffusion-thermo (Dufour) are taken into account. Moreover, the effects of heat source/sink and first order chemical reaction are also considered. The governing flow problem is modelled by means of similarity transformation variables with their relevant boundary conditions. Finally, the reduced nonlinear coupled ordinary differential equations are solved numerically by means of nonlinear shooting technique. The effects of all the governing parameters are discussed for velocity, microrotation, temperature, concentration profiles, shear stress, transfer rate of heat and mass are presented with help of graphs. Numerical comparison is also presented with the existing published results as a special case of our study.
