摘要: Abstract Absorptance measurements of selected resolved spectral lines in the OH 2 Σ + − Π (0, 0) band near 3100 A have been used to compute ground electronic state hydroxyl radical concentrations and rotational temperatures for high-intensity continuous combustion hydrogen/air methane/air mixtures a jet-stirred reactor. For mass throughput rates between 3 x 10−2 gm/cm3 sec fuel/air equivalence ratios, Φfuel/air, varying from 0.57 1.32, maximum (OH) 1 1016 cm−3 occurred Φfuel/air = 0.85 Ground-state were slightly greater than gas kinetic determined thermocouple uncorrected heat losses. An estimate vibrational temperature implied that degrees freedom also equilibrium. Values deduced collisional broadening parameter, a, agreed favorably with previous results.
