由于代用燃料所占份额越来越大，需要对代用燃料，特别是含氧生物衍生燃料成分的燃烧进行描述。层流燃烧速度是表征燃料特性的关键参数之一，也是验证化学动力学模型的重要参数。在球形燃烧容器中进行了甲醇、乙醇、正丙醇和正丁醇的层流燃烧速度实验，未燃温度为373K，压力为10bar。从这项研究和已发表的文献中测得的燃烧速度与已发表的化学机理的数值模拟数据进行了比较。这些模型往往低估了实验测量值。敏感度分析建议进一步研究燃料与氢和羟基自由基反应的压力依赖性。(C)2013爱思唯尔有限公司。保留所有权利。
Due to their increasing share, the combustion of alternative fuels and in particular oxygenated, bioderived fuel components need to be characterised. The laminar burning velocity is one key parameter for the characterisation of fuels, and it also serves as an important quantity to validate chemical kinetic models. Methanol, ethanol, n-propanol, and n-butanol laminar burning velocities experiments were conducted in a spherical combustion vessel at an unburnt temperature of 373 K and a pressure of 10 bar. Measured burning velocities from this study and from the published literature are compared with numerical simulation data from published chemical mechanisms. The models tend to underpredict the experimentally measured values. A sensitivity analysis suggests further investigation of the pressure dependence for the fuel specific reactions with hydrogen and hydroxyl radicals. (C) 2013 Elsevier Ltd. All rights reserved.
