000014499 520__ $$2eng$$aThis study examines the effect of upstream disturbances on the unsteadiness of a 3D shock-wave boundary-layer interaction generated by a swept-ramp in a Mach 2 flow. The disturbances studied are present in the undisturbed upstream boundary layer or imposed by a pulsed-jet actuator operating at kilohertz rates. A number of diagnostic techniques are employed, including surface flow visualization, fast-response surface pressure measurements, planar laser scattering and high resolution planar and stereo PIV. Previous work in this facility has identified a correlation between upstream disturbances and unsteadiness in 2D interactions. However, swept ramp interactions exhibit an “open” separated flow that does not recirculate. Open interactions are likely have significantly different unsteadiness mechanisms in comparison to 2D interactions. This work is part of an on—going study that seeks to better understand driving mechanisms of low-frequency unsteadiness in 3D interactions.
