Abstract : Solutions to three dimensional, compressible, laminar boundary layer equations were obtained for the cases of cones at incidence to nonuniform supersonic free stream flows. The boundary layer equations were placed in a Crocco-type form which makes use of similarity variables. A solution method is employed where the equations are converted to a finite difference form using a scheme which is stable for both negative and positive transverse velocities. The inviscid data used in the study are computer solutions and the cases include circular cones in shear flows and in axisymmetric wake flows. The results from several solutions of the exact boundary layer equations were compared with results from a small crossflow model.
