Abstract:

Progress is reported for an interdisciplinary program aimed at establishing advanced optical diagnostic techniques applicable to combustion and plasma flows. The primary effort is on digital flowfield imaging techniques, which offer significant potential for a wide range of spatially resolved 2-d and 3-d measurements. The imaging is accomplished by recording light scattered from a planar laser-illuminated region using a modern solid-state camera. The scattering process is generally laser-induced fluorescence, though Mie, Rayleigh and Raman scattering may also be used. Activities reported include 1image processing of PLIF data 2 PLIF imaging in nonequilibrium shock tube flows 3 temperature and velocity imaging in supersonic flows 4 concept for simultaneous measurement of multiple parameters 5 digital camera for high- speed imaging 6 plasma diagnostics 7 laser photolysis shock tube and 8 cw UV laser absorption diagnostics. Keywords Two-dimensional three-dimensional flow Laser applications Light scattering PLIFPlanar Laser-Induced Fluorescence Continuous-wave ultraviolet laser absorption Optical measurements data High temperature gas dynamics.
