Abstract

The influence of the quantum corrections for the rate constants of the chemical reactions on the spontaneous ignition time of hydrogen-containing mixtures was studied. It is shown that at high pressures (30-100 atm) and relatively low temperatures (700-900 K) introduction of quantum corrections to rate coefficient for reac-tion H2+O2->2OH leads to better agreement between the predicted ignition time of hydrogen containing mixtures and published results of measurements.
