MHD Stagnation Point Flow and Heat Transfer of a Micropolar Fluid in a Porous Medium

Abstract

In the present paper, an analysis is carried out to study the steady laminar flow of an incompressible electrically conducting micropolar fluid impinging on a permeable flat plate in a porous medium in the presence of transverse magnetic field. The effect of viscous dissipation is taken into account. The governing boundary layer equations are transformed to a system of nonlinear ordinary differential equations by taking suitable similarity variables. The resulting equations are solved numerically using Runge-Kutta method accompanied with Shooting Technique. The effects of various parameters such as porosity, magnetic, material, prandtl number and the Eckert number for corresponding velocity and temperature field have been discussed in detail through graphical representation.
