A Diffusion-thermo effect on MHD convective flow of a viscoelastic fluid through a porous medium past an oscillating porous plate in slip flow regime

Abstract

In this article, we studied an unsteady flow of an eclectically conducting and incompressible viscoelastic liquid of the Walter's ${B}'$ model with simultaneous heat and mass transfer near an oscillating porous plate through a porous medium with diffusion-thermo, chemical reaction, heat source in the slip flow regime under the influence of a uniform strength transverse magnetic field. The governing equations of the fluid flow fields are solved by a regular perturbation method for small elastic parameter, and the expressions for the velocity, temperature, concentration, skin friction, Nusselt number, and Sherwood number are obtained. The effects of the important flow parameters on the fields are discussed graphically. The existence of the viscoelastic parameter and the rarefaction parameter causes the velocity of the fluid to decrease.
