Chemical Reaction And Radiation Effects On Magnetohydrodynamic Convective Flow In Porous Medium With Heat Generation

The present paper focus on simultaneous effects of thermal and concentration diffusions in
unsteady magnetohydrodynamic free convection flow past a moving plate maintained at
constant heat flux and embedded in a viscous fluid saturated porous medium is presented. The
transported model employed includes the effects of thermal radiation, heat source and chemical
reaction. Te fluid is considered as a gray absorbing – emitting but non-scattering medium and
the Rosseland approximation in the energy equation is used to describe the radiative heat flux
for optically thick fluid. The dimensionless coupled linear partial differential equations are
solved by suing perturbation technique. The solution for the velocity, temperature and
concentration as well as the skin friction coefficient and the rates of heat and mass transfer are
shown graphically for different values of physical parameters involved.
