- Аннотация: Influence of electron excited singlet delta oxygen (SDO) molecules produced in direct current (DC) glow discharged plasma on the induction length decrease in the H2-O2 mixture has been studied via comprehensive two-dimensional (2D) numerical simulations. The influence of different species from discharge on induction length was revealed. Two stages specify the ignition time decrease for the studied conditions: (i) chain initiation in reactions with residual odd oxygen; and (ii) the following chain-branching enhancement due to reaction H + O2(1Dg) -> O + OH. The last reaction is the key process for studied conditions when concentration of SDO exceeds 4%. The estimated rate constant of this reaction was found to be about 2.5·10−13 cm3/s at 780 K.
