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.
