Viscoelastic fluid, Velocity slip, Magnetohydrodynamic, Porous medium, Viscous dissipation, Thermal radiation

In this paper, we analytically study about the boundary layer flow and heat transfer on

non-Newtonian fluid which in particular is the viscoelastic fluid. The

magnetohydrodynamic (MHD) slip Darcy flow of viscoelastic fluid over a stretching

surface in a porous medium with the presence of thermal radiation and viscous

dissipation is examined. The results for two viscoelastic fluids which is elastico-viscous

fluid and second grade fluid are obtained and compared. The governing partial

differential equations are reduced to non-linear ordinary differential equations with

the aid of similarity transformation, which are then solved analytically by using exact

analytical method. The effects of the physical parameters on the velocity and

temperature fields are presented through graphs and are discussed. Skin friction and

heat transfer coefficients are computed and analysed.
