Heat and Mass Transfer Effects on a Dissipative and Radiative Visco-Elastic MHD Flow over a Stretching Porous Sheet

Abstract

The objective of the present study is to consider a dissipative and radiative visco-elastic flow over a stretching porous sheet. The applicability of the present study is numerous in the polymer industry in stretching of sheets with dissipative environment. In view of its scope, the present study brings the work of Khan (Int J Heat Mass Transf 49, 1534–1542, 2005) and Singh (Int Comm Heat Mass Transf 35, 637–642, 2008) as particular cases. The solution of the momentum equation has been taken care of by similarity transformation and applying a particular solution satisfying boundary conditions. Further, the heat and mass transfer equations are solved by applying the confluent hypergeometric function (Kummer’s function). It is interesting to note that the presence of elastic element in the fluid, external magnetic field and suction at the plate reduce the skin friction favoring the stretching of sheets whereas heat loss has been minimized due to permeability of the medium, presence of heat source in case of low diffusive fluid.
