项目摘要

The purpose of present project is to construct detailed chemical kinetic mechanism for practical fuels. To this end, detailed chemical kinetic mechanisms of various alkane fuels have been developed. In order to validate the kinetic mechanisms, simulation results were compared with the experimental ignition delay data of various alkane fuels.Unified kinetic mechanism for butane has been constructed at first. This mechanism could be applied for fuels containing CH4, C2H6, C3H8, n-C4H10, and iso-C4H10. Next, detailed chemical kinetic mechanism for PRF (Primary Reference Fuel ; mixtures of n-penatne and iso-octane) has been constructed by using program package KUCRS developed by Miyoshi. This mechanism was also validated with the shock tube ignition delay data Toluene combustion mechanism was also generated in this project. By combining these kinetic mechanisms for PRF and toluene, simulation of surrogate fuels for gasoline became possible. In addition, combustion mechanisms for xylenes are also constructed. There are three isomers of xylene. Kinetic differences of these three isomers are included in the present mechanism. Since ignition characteristics of hydrocarbons are very different form different isomers, it is very important to include chemical kinetic difference of these isomers.For the fuels of next generation, addition of oxygen-containing chemical species such as alcohols and ethers is examined. In order to understand the ignition characteristics of those oxygen-containing fuels, chemical kinetic mechanisms for ethanol and ETBE (Ethyl-Tert-Butyl Ether) were also generated. Effects of addition of those oxygenated fuels to the PRF on the ignition delay times were simulated by using kinetic mechanism for the mixtures of PRF and ETBE or ethyl-archol.Shock tube experiments to measure the ignition delay times for the fuels considered in the present study were performed. Those shock tube data were used to validate the kinetic mechanism obtained in the present study.
本课题的目的是为实际燃料建立详细的化学动力学机理。为此,已经开发了各种烷烃燃料的详细化学动力学机制。为了验证动力学机理,将模拟结果与各种烷烃燃料的着火延迟实验数据进行比较,首先构建了丁烷的统一动力学机理。该机理可应用于含有CH 4、C2 H6、C3 H8、n-C4 H10和iso-C4 H10的燃料。其次,利用Miyoshi开发的KUCRS程序包,建立了正戊烷和异辛烷混合物的PRF(Primary Reference Fuel ; mixtures of n-penatne and isooctane)的详细化学动力学机理。该机理也得到了激波管点火延迟数据的验证。通过结合PRF和甲苯的这些动力学机制,模拟汽油的替代燃料成为可能。此外,还建立了二甲苯的燃烧机理。二甲苯有三种异构体。这三种异构体的动力学差异包括在本机制中。由于碳氢化合物的着火特性与不同异构体有很大的不同,因此考虑异构体的化学动力学差异是非常重要的,对于下一代燃料,研究了添加含氧化学物种如醇类和醚类。为了了解这些含氧燃料的点火特性,乙醇和ETBE(乙基叔丁基醚)的化学动力学机制也被产生。采用动力学机理模拟了在PRF中加入含氧燃料对点火延迟时间的影响,并利用激波管实验测量了这些含氧燃料的点火延迟时间。这些激波管数据被用来验证本研究中得到的动力学机制。
