Abstract
New laser-based diagnostic techniques, developed primarily within the combustion community, offer considerable promise for measurements in reactive gaseous flows. In this paper we overview three diagnostic methods under development at Stanford University: spectrally resolved line-of-sight absorption (LOSA), conducted with wavelength-modulated semiconductor diode and ring dye laser sources; spectrally resolved single-point laser-induced fluorescence (SP LIF), conducted with a rapid-tuning ring dye laser; and planar laser-induced fluorescence (PLIF), conducted with a tunable pulsed dye laser source and intensified CCD array camera. These methods have unique capabilities for nonintrusive measurements of flow- field properties such as temperature, species concentration, velocity, density and pressure, as well as quantities derived from these properties such as mass flux (product of velocity and mass density). Species monitored in current studies include NO, OH, O2 and H2O.
