Abstract

Spontaneous emission signal had different curves of kerosene’s auto-ignition in shock tube under different temperature conditions, and OH* radicals concentration time history was numerically investigated. Two component surrogate fuel model (n-decane+trimethylbenzene) was used to validate consistency of its ignition delay time data with kerosene. Then simulation of OH* time history during reaction was carried out using the surrogate fuel model’s combustion mechanism. OH* radicals’ sensitivity analysis and reaction paths of production and consumption were investigated under different temperatures. The results show that the difference of dominant reactions for radicals’ consumption lead to different curves of OH* radicals traces, which was that two peaks curve would present more easily under lower temperature and one peak curve under higher temperature.
