Abstract : Transonic normal shock - turbulent boundary layer interactions can significantly influence not only the local viscous flow but also the downstream behavior of the boundary layer on aerodynamic bodies. It is therefore important that fundamentally-based analytical tools be developed for describing and scaling these interaction effects. This paper examines recent progress toward this goal, with emphasis on two aspects. (1) A basic non-asymptotic triple-deck theory of non-separating two-dimensional interactions that is applicable over a wide range of practical Reynolds numbers and boundary layer profile shapes. (2) Its applicable as a local 'interactive module' in the global transonic flow field analysis of wings, including detailed comparisons with experimental data. Also discussed is the adaptability of this theory to treat interactions involving non-adiabatic wall conditions, including the prediction of incipient separation.
