title = "Oblique wave disturbance analysis of supersonic flow past axisymmetric and 2D bodies at angles of attack",
abstract = "Boundary layer stability analysis performed through application of the parabolized stability equations (PSE) has been shown to provide accurate calculations of second-mode two-dimensional wave disturbances.1 For supersonic flows, between approximately Mach one and five, two-dimensional wave disturbances are usually not the most unstable distur bance inside a boundary layer, and the oblique wave disturbance, which is an extension of the Tollmien-Schlichting instability in incompressible flows, commonly becomes the most amplified disturbance. This paper demonstrates the use of the STABL software suite to calculate accurate first or second-mode oblique wave disturbances. Calculated oblique wave amplification rates and wave angles show very good agreement to previously-published data of supersonic flow over flat plates and cylinders. This analysis is then extended to a blunt wedge at angles of attack to show the impact on the stability results when testing for oblique and two-dimensional disturbances.",
