Abstract : In the present work the general formulation and a method for solving a viscous, radiating, non-similar boundary layer flow in thermal equilibrium are presented. The formulation and the solution include both radiative emission and absorption and are therefore valid for the entire range of optical thicknesses, from thin to thick. To illustrate the actual use of the suggested method the problem of a radiating boundary layer over a flat plate was solved. The solutions indicate the decrease of temperatures, their gradients and the related conductive heat transfer to the wall as well as the direct contribution of radiation to the net heat flux. When the external flow is cold and radiation effects are restricted to a thin hot boundary layer, the decrease of the conductive heat transfer, induced by the presence of radiation, was found to be larger than the contribution of radiation to the net heat flux to the wall.
