Abstract:
Two laser-spectroscopic techniques for measurements in reacting and nonreacting air flows have been investigated. The feasibility of temperature measurement in nonequilibrium flows using laser-induced O₂ fluorescence was analyzed. A multi-photon N₂ ionization process using a frequency-tripled Nd:YAG laser was identified through a series of experiments. The process was assessed for its application to temperature measurement and time-of-flight velocimetry.
