Аннотация:A comprehensive numerical study of ignition in the H2-O2 mixture with DC-discharge activation for the experimental conditions [1] was carried out. The influence of singlet oxygen on the initiation and branching chain reactions of combustion in hydrogen-oxygen mixtures was analyzed. The sensitivity of the induction length to the total rate constant was revealed. The probability of branching channel in the reaction H+O2(1Δg) was observed depending on the value of the total rate constant. The estimated value of the reaction rate H+O2(1Δg)→O+OH equals (2.4±0.2)∙10-13 at 780K.
