Abstract:
The nonequilibrium radiation arising from the ignition of a $10\%$ stoichiometric hydrogen-oxygen mixture doped with combustion inhibitors and diluted with argon behind shock waves was studied. The addition of halogen-containing inhibitors led to increased UV radiation around the $220$ and $411$ nm wavelengths characteristic of the $\mathrm{HO}_2$ radical and $\mathrm{H}_2\mathrm{O}_2$ and $\mathrm{H}_2\mathrm{O}$ molecules, instead of the expected reduction in the super-equilibrium radiation of active radicals in the ignition zone. Therefore, the hypothesis about the inhibition mechanism due to extinguishing by the excited $\mathrm{H}\mathrm{O}_2^*$ radical is not confirmed, and the effect of inhibiting additives is due to the binding of $\mathrm{H}$ and $\mathrm{O}$ atoms.
