| 内容記述 | Transmittance measurements using an NO resonance source are reported for an expanded arc-heated flow. The data are used to deduce NO concentrations, which range from 0.17 to 1.9 percent by volume for facility operating conditions with nozzle exit static temperatures from 87 to 320 K. Absorption measurements in the (0,1) band, not attributable to a flow at thermal equilibrium, are used to calculate nonequilibrium vibrational temperatures ranging from 533 to 919 K. The data are in good agreement with the vibrational-temperature predictions of a one-dimensional relaxation code, within the uncertainties of calculations and measured transmittance. |
