Investigation of Test Facility Effects on the Three-Dimensional Boundary Layer Interaction.
Abstract
A continuing uncertainty when correlating three-dimensional shockwave/turbulent boundary layer interaction data obtained from different wind tunnel facilities is the extent of 'facility-peculiar' effects on the test data, particularly the effect of free-stream Reynolds number. The present study investigates the pressure and heat transfer data in the interaction region taken at Mach 3 in three different facilities to determine the degree of dependency of the data on facility effects. The study shows that, for constant Mach number, the interaction data are essentially independent of facility effects or can be made independent through proper modification. The report also provides general data illustrating the physics of the interaction process for comparison with previous studies and to add to the general data base on three-dimensional interactions.
