Radiative Effects on Heat and Mass Transfer of Magnetohydrodynamics Fluid Flow in Porous Media

Magnetohydrodynamics (MHD) flow involving heat and mass transfer under the influence of radiation, heat source, and chemical reaction effects is of great concern in physical sciences and engineering. The gap in earlier studies showed that few parameters emanating from studies like this, due to difficulty usually encountered in reaching quick convergences when solving such problems. The study therefore, investigated radiative heat and mass transfer of MHD fluid flow effects in porous media. The Partial Differential Equations (PDEs) formulated were reduced to a set of nonlinear Ordinary Differential Equations (ODEs) by similarity transformations which were solved using fourth-order Runge-Kutta method with shooting technique using Maple 18 software. The study concluded that the increase in radiation and heat generation had significant effects on the MHD fluid flow in porous media over stretching surface. The study therefore recommended the use of increased renewable energy in metallurgical applications, plastic extrusion and MHD power generation systems.
