Abstract : A complete discussion is presented of the chemically reacting laminar boundary layer. Included in the study are separate homogeneous and hetergeneous reactions; additionally there is considered the problem of simultaneous gas phase and wall reaction. The basic solution, under conditions of unit transport properties, i.e., mass densityviscosity product constant, Prandtl number and Schmidt unity, were derived using previous devised operator techniques. For gas phase reaction the solution for the species distribution is seen to reduce to an integral equation; the temperature arising by quadrature. It is shown that simple first order results for chemistry of the usual complexity occuring in hypersonic boundary layer flows can be obtained without resort to large scale computation. The flow over a catalytic wall are derived from unit solutions to the basic problem. Using the present techniques any distribution of wall catalycity is permissable including discontinuities. Results of this analysis are shown to agree well with previous solutions. In all cases extension to non-unity transport properties are presented. Except in limited studies these extensions are not carried out because analyticity of all solutions was desired. Since no previous solution to the combined problem are available, new first order results were obtained corresponding to the leading edge solution. (Author)
