Advanced Diagnostics for Reacting Flows
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: 1)image 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; PLIF(Planar Laser-Induced Fluorescence); Continuous-wave ultraviolet laser absorption; Optical measurements data; High temperature gas dynamics.
