- Abstract
- The possibility of a global reaction model to predict the autoignition delay times of stoichiometric fuel-air mixtures with the accuracy corresponding to that obtained using the most comprehensive chemical mechanisms is demonstrated. To make the global reaction model applicable in a wide temperature range, the effective kinetic parameters are set temperature dependent. These parameters are derived for alkane (from methane to n-heptane and alkene (ethylene and propylene) fuels. Complicated and non-monotonic dependencies of autoignition delay time on temperature, such as those in which an interval with negative temperature dependence exist, are replicated. Compared to the detailed chemical mechanisms, use of the global reaction model offers considerable reduction of computational cost yet retaining capability of predicting critical phenomena of flame extinction and re-ignition in under-ventilated or strained flames.
