Soret and radiation effects on MHD chemically reactive Nano fluid flow over an exponentially accelerated vertical plate with ramped wall temperature and ramped surface concentration through porous medium

Abstract

Present paper is concerned with the study of flow, heat and mass transfer characteristics in the unsteady natural convective magneto hydrodynamics flow of chemically reactive electrically conducting Nano fluid past over an exponentially accelerated vertical plate in the presence of soret and thermal radiation. It is assumed that the bounding plate has ramped temperature with ramped surface concentration and isothermal temperature with ramped surface concentration profile through uniform porous medium. The governing non- dimensional partial differential equations are solved analytically using Laplace transform technique. The features of the fluid flow, heat and mass transfer are analyzed for all parameters by plotting graphs. Skin friction, Nusselt number and Sherwood number are obtained and represented through tabular form
