Abstract: The role of chain branching and termination reactions in the inhibition and promotion of hydrogen-oxygen flames was studied numerically. Based on the results of sensitivity analysis, methods were proposed for estimating the effectiveness of flame inhibition and promotion based on the net rate of formation of hydrogen atoms and the burning velocity sensitivity coefficients to the branching rate constant. The effect of the heat release rate in recombination reactions involving inhibitors and promoters on the flame propagation velocity was studied.

Keywords: hydrogen-oxygen flame, inhibition, promotion, mechanism of chemical reactions in flame, organophosphorus compounds, sensitivity analysis.
