Abstract

The study on methane–oxygen mixture ignition diluted with nitrogen by numerical simulation was carried out. Temporal sweeps of CH₃, CH₄, OH, and O₂ concentrations were obtained for three variants of the combustible mixture in a wide temperature range T = (700–2500) K. The temperature intervals of ignition with the mechanism of active radicals’ chain branching were established. Ignition temperatures in these intervals were determined. The induction time and the corresponding reduced induction time for the three ignition signs were calculated in the determined temperature intervals for the three variants of the mixtures. A satisfactory agreement between the values of the calculated induction time and the published measured values was established.
