Abstract:
A two-dimensional inviscid compressible flow over an arbitrarily shaped surface irregularity immersed in single or double wall-layer streams parallel to a supersonic main stream is analyzed. Solutions for single-layer streams are obtained on a linearized two-dimensional basis for the complete flow field. Solutions for double-layer streams are obtained on a linearized quasi onedimensional basis for the layer streams and on a linearized two-dimensional basis for the main stream. The double-layer stream is considered as an idealization of a boundary layer, and has possible application to the determination of the influence of a boundary layer on the wave drag of a surface irregularity submerged in the boundary layer. Comparison of pressure distributions and wave-drag calculations by the quasi one-dimensional method with limited experiments is not completely satisfactory for dominantly subsonic layer streams, but holds promise for turbulent boundary layers for Mach numbers around 2.0 and higher.
