Radiation and Chemical Reaction Effects on Unsteady Magnetohydrodynamics Boundary Layer Fluid Flow in Porous Media

Abstract

This study was conducted to investigate radiation and chemical reaction
effects on unsteady MHD boundary layer flow in porous media over an
exponentially stretching surface. In the study, boundary layer flow, heat
and mass transfer of incompressible viscous unsteady MHD fluid over
porous stretching vertical surface in the presence of thermal radiation
was investigated. A similarity transformation was used to reduce the
governing system of partial differential equations (PDEs) to a set of
nonlinear Ordinary Differential Equations (ODEs) which were solved
numerically using computer embedded fourth-order Runge-Kutta method
with shooting technique. The results showed that an increase in radiation
produced a rise on the velocity, temperature and concentration profiles.
Skin friction, Nusselt and Sherwood numbers increased with increasing
radiation.
