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 EddiesFluid mechanics Flow visualization.
