ABSTRACT: The objective of present work is to study the thermo diffusion
effect on an unsteady simultaneous convective heat and mass transfer flow of an
incompressible, electrically conducting, heat generating/absorbing fluid along
a semi-infinite moving porous plate embedded in a porous medium with the
presence of pressure gradient, thermal radiation field and chemical reaction.
It is assumed that the permeable plate is embedded in a uniform porous medium
and moves with a constant velocity in the flow direction in the presence of a
transverse magnetic field. It is also assumed that the free stream consists of
a mean velocity, temperature and concentration over which are super imposed an
exponentially varying with time. The equations of continuity, momentum, energy
and diffusion, which govern the flow field, are solved by using a regular
perturbation method. The behavior of the velocity, temperature, concentration,
Skin-friction, rate of heat transfer and rate of mass transfer has been
discussed for variations in the physical parameters. An increase in both Pr and
R results a decrease in thermal boundary layer thickness. However, concentration
decreases as Kr, Sc increase but it increases with an increase in both So and δ.
