An Interaction Model for Supersonic, Laminar Separating Flows,
Abstract
An analytical model and computer program has been developed to analyze supersonic, laminar separating flow fields over ramps. The important features of the model are its ability to include the two family nature of the supersonic flow field, the matching of supersonic and subsonic profiles in the transonic region (which aids in the selection of the solution for a particular problem when two exist, thus eliminating the problem of branching solutions), the inclusion of the normal momentum equation (and thus normal pressure gradients) throughout the flow field, and the solution of the separation problem by a marching technique. The ellipticity of separated flow fields is accounted for by casting the problem into one of the inverse nature. Correlations with data are utilized to determine upstream influence properties. Results for pressure distribution and heat transfer are presented and compared with experimental data. The applicability of the model to more general flow fields and geometries is assessed. (Author)
