An Analysis of Transonic Viscous/Inviscid Interactions on Axisymmetric Bodies with Solid Stings or Real Plumes
Abstract
A numerical and theoretical investigation of pressure distribution predictions over arbitrary bodies of revolution in transonic flow has been carried out. Special features of the study include a comprehensive survey of previous and contemporary efforts in this direction and a detailed description of a combined viscous/inviscid digital computer program which was developed to iterate between the inviscid transonic and the viscous portions of the analysis. For attached boundary layers the calculation procedure has been fully automated for both subcritical and supercritical cases, and predicted pressure distributions agree well with data. The entrainment effect of a real plume was modeled using the mixing theory first developed by Chapman and Korst. This method shows promise when its results are compared with data, but further work must be done to more correctly model the turbulent mixing of the two jets.
