Abstract:
The effect of quantum corrections to the rate constants of chemical reactions on the time of thermal ignition of hydrogen-containing mixtures is studied. It is shown that, at high pressures $(30$–$100)$ atm and temperatures in the range of $(700$–$900)$ K, accounting for the quantum corrections to the initiation reaction $\rm H_2 + O_2 \to 2OH$ brings the data on the calculated ignition delay times of the hydrogen-containing mixture into agreement with the previously published results of measurements.
