An experimental investigation of large-scale structures in supersonic reattaching shear flows
… at reattachment, and in the wake region of a supersonic base flow. Single-pulse side and end views were obtained at several streamwise locations to characterize the evolution and three-dimensionality of the large-scale motions. From statistically significant ensembles, spatial correlation …

Empirical mode decomposition applied to planar and volumetric velocity field measurements of a supersonic separated flow
The supersonic separated flowfield aft of a blunt-faced cylinder aligned with the freestream is highly complex such that a technique able to identify instantaneous turbulent structure within it is valuable. In this study, multi-dimensional extensions of fast and adaptive empirical mode …

Active control of massively separated high-speed/base flows with electric arc plasma actuators
… arc plasma actuators on high-speed separated flows. Two underlying goals motivated these experiments. The first goal was to provide a flow control technique that will result in enhanced flight performance for supersonic vehicles by altering the near-wake characteristics. The second goal was to …

Stereoscopic PIV measurements and proper orthogonal decomposition of a supersonic axisymmetric base flow
The supersonic flow separating past a cylindrical afterbody generates a complex, compressible and highly turbulent flowfield. This flow models several realistic applications, such as the wake region behind projectiles, bullets and unpowered rockets. A blowdown-type supersonic wind tunnel built …
