The local similarity solution procedure was successfully adopted to investigate non-Darcian flow and heat transfer through a boundary layer developed over a horizontal flat plate in a highly porous medium. The full boundary layer equations which consider the effects of convective inertia, solid boundary and porous inertia in addition to the Darcy flow resistance, were solved using novel transformed variables derived from a scale analysis. The results from this local similarity solution are found to be in good agreement with those obtained from the finite difference method. The effects of the convective inertia term, boundary viscous term and porous inertia term on the velocity and temperature fields are examined in detail. Furthermore, useful asymptotic expressions for the local Nusselt number were derived in consideration of possible physical limiting conditions.
