讲座摘要：
To reduce emissions and increase efficiency of combustors research groups throughout the world are performing fundamental studies of fuel oxidation. These include both conventional fossil fuels and alternative biofuels, which are typically oxygenated hydrocarbons. Characteristic reaction times in combustors require the study of fuel oxidation at the millisecond to microsecond timescale. To reproduce these conditions the community use facilities such as rapid compression machines, shock tubes, jet-stirred reactors, flow reactors etc. These can be simulated using detailed chemical kinetic mechanisms which describe the oxidation of a fuel in a combustor at the molecular level and help elicit the underlying chemistry responsible the fuel oxidation. Real fuel are blends of approximately 100 or more different compounds comprising n-alkane, branched alkanes, cycloalkanes, olefins, and aromatics and can also have oxygenated species (e.g. ethanol added). To generate accurate chemical kinetic mechanisms to describe these real fuels it has become common practice within the community to use surrogate mechanisms which contain a small number of species which act as a surrogate for the fuel component. In this seminar the methodology in the development of such mechanisms will be discussed.
