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.

 

讲座人介绍

Henry Curran is a Professor of School of Chemistry at NUI Galway. He received his PhD degree from the National University of Ireland, Galway (NUIG) in experimental and numerical studies of combustion kinetics in 1994 and a DSc. degree by research from the National University of Ireland in October 2011. He served as a postdoctoral research scientist from 1994 to 1997 and research scientist in combustion modelling from 1997 to 1999 at Lawrence Livermore National Laboratory. He is currently director of the Combustion Chemistry Centre at NUIG and is a member of the editorial boards of “Progress in Energy and Combustion Science”, “Combustion and Flame” and the “Proceedings of the Combustion Institute”. He is a founder member of the Irish Section of the Combustion Institute, a fellow of both the Institute of Chemistry of Ireland and the Royal Society of Chemistry and a member of the Royal Irish Academy, the Institution of Engineers Ireland, the American Society of Automotive Engineers and the Society of Automotive Engineers. For brilliant research towards the development of combustion kinetic mechanisms, he was designated a Fellow of the Combustion Institute, and was awarded the Boyle Higgins Gold Medal Award Lecture.
