Simultaneous multipoint measurements of density gradients and temperature in a flame. Progress report, July 1, 1984-February 28, 1985
A summary is given of progress in the development and application of nonintrusive optical techniques for making two-dimensional measurements in turbulent reacting flows. Developments in the last year are reviewed, including new results in the following areas: (1) the development of higher framing rate capabilities for two-dimensional imaging experiments, (2) the use of Rayleigh scattering for measuring the instantaneous two-dimensional temperature distribution in a turbulent nonpremixed flame, (3) improvements in Raman imaging for making instantaneous species concentration measurements in turbulent flames, and (4) the combination of Raman and Rayleigh measurements to enable the first simultaneous two-dimensional mapping of both species concentration and temperature in turbulent premixed and nonpremixed flames. A proposed plan for continuation of the diagnostics development effort is presented along with suggestions for the use of data already obtained.
