Radiation and Soret Effect on Visco-Elastic MHD Oscillatory Horizontal Channel Flow With Heat and Mass Transfer in Presence of Chemical Reaction and Heat Source

An analysis of radiation and soret effect on visco-elastic mhd oscillatory flow with heat and mass transfer through a porous medium bounded by two infinite horizontal parallel porous plates in presence of chemical reaction and a heat source has been presented when one plate is kept at rest while the other is oscillating in its own plane. The fluid is considered to be non-Newtonian characterized by Walters liquid (Model B′). The temperature of the stationary plate is assumed to be constant whereas the temperature of the other plate varies periodically with time about a steady mean. The equations governing the fluid flow, heat and mass transfer have been solved analytically. The expressions for velocity, temperature, species concentration, non-dimensional skin-friction at the plates, the coefficient of rate of heat transfer from the plates to the fluid in terms of Nusselt number in non-dimensional form, the coefficient of rate of mass transfer from the plates to the fluid in terms of Sharewood number in non-dimensional form are obtained and illustrated graphically to observe the visco-elastic effects in combination of other flow parameters involved in the solution. It is noticed that the momentum, thermal and concentration fields are significantly affected by the visco-elastic parameter.
