Calculations of thermal ignition time of hydrogen–air mixtures taking into account quantum corrections

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 H₂ + O₂ → 2OH brings the data on the calculated ignition delay times of the hydrogen-containing mixture into agreement with the previously published results of measurements.
