Résumé:	This investigation presents a rigorous experimental, numerical, and analytical study of flow separation and its associated interactions in over-expanded supersonic nozzles. An experimental conical Laval nozzle is used to measure the axial static pressure evolution at various nozzle pressure ratios (NPR). This empirical data is meticulously supplemented by detailed numerical simulations employing three distinct and commonly used turbulence models. Furthermore, the study incorporates an analysis of a typical analytical engineering model and a widely used semiempirical shock wave boundary layer interaction (SWBLI) criterion.
