Abstract : This three-year contract originally had two tasks: to investigate the structure of flat plate supersonic turbulent boundary layers (Task A), and to investigate longitudinal curvature effects in turbulent boundary layers (Task B). As a result of the work performed under these task headings, we identified a need to study the structure of simple, wall-bounded vortex loops. This investigation (Task C) commenced in the third year, and we feel that it has made a major contribution to our understanding of the ensemble-averaged structure of low and high speed turbulent boundary layers. The progress reported here is that achieved in completing these three tasks. Keywords: Turbulent flow; Eddies(Fluid mechanics); Flow visualization.
