ABSTRACT
This dissertation investigates the magnetic field and Soret influence on MHD unsteady
free convection radiating and reacting fluid past an exponentially accelerated inclined
infinite porous plate of uniform permeability with variable temperature and concentration
numerically. In this model the fluid is considered a gray, emitting absorbing
radiation but a non-scattering medium and a magnetic field of intensity B0 is imposed
in the perpendicular direction to the plate. The governing equations of the model are
transformed into dimensionless form by adopting suitable non-dimensional variables
and parameters, then the resulting coupled non-linear PDE´s are solved by the finite
difference method. The influence of flow control parameters on the velocity, concentration
and temperature fields are illustrated graphically whilst numerical results of the
skin friction, Sherwood and Nusselt numbers are displayed in Tables. It is found that
permeability of the medium, thermal and mass buoyancy force improve the fluid velocity
whilst the magnetic field and inclination angle have reverse effect. The fluid
velocity and temperature tends to decrease with an increment in radiation parameter
whilst reverse trend is noticed in case of Nusselt number. The Soret effect is to elevate
the fluid velocity and concentration whilst chemical reaction rate has reverse impact,
and these parameters have opposite effect on the Sherwood number. The progression
of time escalates the fluid velocity, temperature and concentration whilst it has a reverse
effect on the skin friction, Sherwood and Nusselt numbers. This flow model
has various industrial applications in the field of food processing, polymer production,
design of fins, steel rolling,
