Dissociation rate constants for oxygen at temperatures up to 11000 K. (English. Russian original) Zbl 1276.76003
Fluid Dyn. 48, No. 4, 550-555 (2013); translation from Izv. Ross. Akad. Nauk, Mekh. Zhidk. Gaza 2013, No. 4, 148-154 (2013).
Summary: Measurements of the absorption and vibrational temperature evolution of molecular oxygen behind the shock wave front in regimes with temperatures near the front varying over the range 4000-11 000 K made it possible to determine the dissociation rate constant for $$\text{O}{_2}$$ molecules under both thermal equilibrium and nonequilibrium conditions. The dependence of the dissociation rate constant on the ratio $$T{_v}/T$$, that is, on the deviation from the thermal equilibrium conditions, is demonstrated experimentally. The corresponding expression for the two-temperature dissociation rate constant is proposed.
