Note:
SAMs 1.1.1; The objective of this research project is to investigate the effect of incoming boundary layer state on the unsteady dynamics and structure of a transverse jet in a hypersonic cross-flow. The development of hypersonic technology is a key piece of the emerging global space race, and has the potential to revolutionize commercial air transport, space access, and national defense. This project will use novel, state-of-the-art non-intrusive diagnostic tools, advanced data analysis methods, and a unique Mach 7 hypersonic wind tunnel facility at The University of Texas at San Antonio. This research program will be accomplished in three phases: 1) in-depth characterization of a jet issuing into the fully-developed turbulent boundary layer in the floor of the Mach 7 facility; 2) measurements of a transverse jet issuing from a flat plate with various incoming boundary layer states; 3) measurements of a transverse jet issuing from an axisymmetric body with various incoming boundary layer states. Based on preliminary work, it is hypothesized that incoming boundary layer state will have a significant impact on the dynamics and structure of the flowfield of a transverse jet in a hypersonic cross-flow.
