Frédéric Buda, Pierre-Alexandre Glaude, Frédérique Battin-Leclerc, Richard Porter, Kevin J. Hughes, John F. Griffiths

摘要:

本文介绍了如何自动生成详细的动力学机制,获得烷烃的氧化,以及如何这些模型可以导致更好地了解自燃和冷却火焰的风险,在升高的条件下。根据压力、温度和混合物组成的条件,给出了不同自燃现象(如冷焰或两阶段点火)发生的预测实例。三种化合物进行了处理,一个轻烷烃,丙烷,和两个较重的,正庚烷和正癸烷。

英文摘要:

This paper describes how automatically generated detailed kinetic mechanisms are obtained for the oxidation of alkanes and how these models could lead to a better understanding of autoignition and cool flame risks at elevated conditions. Examples of prediction of the occurrence of different autoignition phenomena, such as cool flames or two-stage ignitions are presented depending on the condition of pressure, temperature and mixture composition. Three compounds are treated, a light alkane, propane, and two heavier ones, n-heptane and n-decane.
