Abstract
Based on the analysis of the databases published in the scientific literature and concerned with the reaction rate constants in the H2/O2 system, a new kinetic mechanism is suggested for describing the processes of ignition, combustion, and detonation in hydrogen–oxygen gaseous mixtures. Attention is mainly focused on consideration of a low-temperature region (T < 1000 K) where a chain of reactions of the formation and subsequent decomposition of hydrogen peroxide plays the major role in the system ignition. The proposed mechanism has been tested by comparing computational results with available data on measurement of the ignition-delay time in shock tubes.
