Abstract : The reference temperature method of predicting skin friction coefficients for supersonic flow with heat transfer is described in detail. Techniques which are simple enough for practical engineering application are presented for applying the methods to bodies of revolution consisting of a cone, cylinders, and conical frusta. A sample calculation is carried out, and a significant improvement over the traditional insulated flat plate method is found. The influences of compressibility and heat transfer on the growth of boundary-layer thickness, momentum thickness, and displacement thickness on a flat plate with zero pressure gradient are presented. The literature concerning boundary-layer transition is reviewed, and the influence of several of the more important parameters evaluated. Only the zero angle of attack case is considered. (Author)
