Abstract

The low temperature first ignition of n-butane/air mixtures is studied in this work, using a short chemistry model with all the important isomers. The reaction rates were obtained from the published data. The first ignition delay time and the overall heat release (temperature jump) were obtained analytically in closed form, where the parametric influence can be easily seen. The chain branching leading to a thermal runaway is produced by a competition in the decomposition of the butylperoxy radicals, RO2i = pC4H9O2 and sC4H9O2. The heat released by the low temperature kinetics is able to increase the temperature to high values, greater than the crossover temperature.
