Abstract
In this thesis we study the effect of radiation on the boundary layer flow and heat
transfer of viscous fluid. The Spectral Homtopy Perturbation Method (S-HPM) used
to solve the system of the governing equations. We also determine the convergent
series of the solution. The accuracy and rate of convergence of the solution has been
tested and compared for different orders and the results are presented in tables . The
physical interpretation to these expressions is assigned through graphs.
