We consider the boundary layer regime when the Grashof number Gr is large. Using the appropriate transformation variables, the basic governing equations are first transformed to non-similar boundary layer form and then solved numerically employing the implicit finite difference method together with Keller-box scheme. The numerical results are presented in terms of the streamlines and isotherms as well as the fluid flow and heat transfer characteristics, namely, the local skin-friction coefficient and the local Nusselt number for a wide range of values of the viscosity and thermal conductivity variation parameter, surface waviness and the Prandtl number. %8 2009-06-17
