dc.description.abstract An experimental investigation has been performed into the effects of leading edge bluntness and sweep on the mean flow characteristics of a glancing shock wave turbulent boundary layer interaction. A series of blunt un swept shock generators (ranging in leading edge diameter from O to 1.0 ins) and a series of sharp swept generators (covering angles of sweep from 0 to 75°) were tested at incidences up to 30° at a Mach number of 2.4 and a free stream Reynolds number of 2.6 x 106 m 1. The results obtained, using a combination of oil flow visualisation, static pressure measurements, schlieren photography and vapour screen visualisation, indicate that existing flow field models can be extended to include the more general configurations _ tested. Leading edge diameter was found to be the major parameter controlling the scale of the interaction produced by the blunted models, with model incidence playing a secondary role, even at large distances from the generator. Existing methods for predicting the scale of the un swept sharp generator flow field are shown to provide a reasonable estimate of the variation of upstream influence with Reynolds number. en_UK
