Abstract

analysis of two dimensional unsteady electrically conducting visco-elastic fluid flow through a porous medium has been carried out in this paper in presence of simultaneous heat and mass transfer. The porous medium is bounded by two horizontal plates moving in opposite directions. The visco-elastic fluid is characterized by Walters liquid (Model ). A magnetic field of uniform strength B0 is applied in the direction perpendicular to the plate. The suction at the plate is assumed to be periodic in nature. The governing equations of fluid motion are solved analytically by using perturbation scheme. The effects of visco-elastic parameter on the governing fluid motion are analyzed graphically for various values of flow parameters involved in the solution. .
