Abstract:

This report summarizes the research findings of a project which has been jointly funded by the Air Force Office of Scientific Research and the National Bureau of Standards. The goal of the research was to improve the fundamental understanding of chemically reacting turbulent flow. The approach which was taken was to investigate mixing in variable density flows in order to better understand the role of local density fluctuations which result from chemical heat release on the turbulent mixing behavior. The development of new experimental diagnostics having excellent spatial and temporal resolution is described. These techniques have been utilized to investigate a wide range of mixing properties in variable density flows. These results are summarized along with a discussion of their importance to an improved understanding of chemically reacting flow.
