Abstract
This paper presents the study of convective heat and mass transfer characteristics of an incompressible MHD visco-elastic fluid flow immersed in a porous medium over a stretching sheet with chemical reaction and thermal stratification effects. The resultant governing boundary layer equations are highly non-linear and coupled form of partial differential equations, and they have been solved by using fourth order Runge-Kutta integration scheme with Newton Raphson shooting method. Numerical computations are carried out for the non-dimensional physical parameters. Here a numerical has been carried out to study the effect of different physical parameters such as visco-elasticity, permeability of the porous medium, magnetic field, Grashof number, Schmidt number, heat source parameter and chemical reaction parameter on the flow, heat and mass transfer characteristics.
Highlights
In recent years, a great deal of interest has been generated in the area of heat and mass transfer of the boundary layer flow over a stretching sheet, in view of its numerous and wide-ranging applications in various fields like polymer processing industry in particular in manufacturing process of artificial film and artificial fibers and in some applications of dilute polymer solution

All these studies deals with the studies concerning non-Newtonian flows and heat transfer in the absence of magnetic fields, but present years we find several industrial applications such as polymer technology and metallurgy [18], where the magnetic field is applied in the visco-elastic fluid flow
Summary
A great deal of interest has been generated in the area of heat and mass transfer of the boundary layer flow over a stretching sheet, in view of its numerous and wide-ranging applications in various fields like polymer processing industry in particular in manufacturing process of artificial film and artificial fibers and in some applications of dilute polymer solution. Abel and Veena [17] studied the viscoelasticity on the flow and heat transfer in a porous medium over a stretching sheet All these studies deals with the studies concerning non-Newtonian flows and heat transfer in the absence of magnetic fields, but present years we find several industrial applications such as polymer technology and metallurgy [18], where the magnetic field is applied in the visco-elastic fluid flow. Seddeek studied the thermal radiation and buoyancy effect on MHD free convection heat generation flow over an accelerating permeable surface with the influence temperature dependent viscosity [30], and later the chemical reaction, variable viscosity, radiation, variable suction on hydromagnetic convection flow problems were included [31,32,33]. We make an attempt to investigate the problem of convective heat and mass transfer of incompressible MHD visco-elastic fluid embedded in a porous medium over a stretching sheet under a chemical reaction. The results are analyzed for various physical parameters such as visco-elasticity, permeability of the porous medium, magnetic field, Grashof number, Schmidt number, Prandtl number, heat source parameter and chemical reaction parameter on the flow, heat and mass transfer characteristics
