Abstract
This investigation presents an analytical study on magnetohydrodynamic (MHD), convective flow of a viscoelastic, incompressible, radiative,
chemically reactive, electrically conducting and rotating fluid through a porous medium filled in a vertical channel in the presence of thermal
diffusion. A magnetic field of uniform strength is applied along the axis of rotation. The fluid is assumed to act on with a periodic time variation of
the pressure gradient in upward direction vertically. One of the plates is maintained at non-uniform temperature and the temperature difference of
the walls of the channel is assumed high enough that induces heat transfer due to thermal radiation. The analytical solutions are obtained for
velocity, temperature and concentration, by solving the dimensionless governing equations using regular perturbation technique. To assess the
effects of various parameters involved in the model, two cases of small and large rotations have been considered. Effects of various parameters
involved in velocity, temperature, species concentration distributions and the corresponding amplitude and the phase angle of the skin friction,
Nusselt number and Sherwood number are shown graphically and discussed in detail.
