摘要: This paper reviews five laser-induced fluorescence-based velocimetry techniques that have been used to study high-speed compressible flows at NASA Langley Research Center. The discussed in this include nitric oxide (NO) molecular tagging (MTV), nitrogen dioxide photodissociation (NO2-to-NO) MTV, and NO atomic oxygen (O-atom) Doppler-shift-based velocimetry. Measurements of both single-component two-component velocity performed using these techniques. details the specific application experiment for which each technique has used, facility was performed, experimental setup, sample results, a discussion lessons learned from experiment.
