Currently, the growth of the commercial space, aviation, and other industries worldwide is accompanied by an increase in negative impacts from harmful CO2 emissions on the atmosphere. However, the transition to biofuel may help solve this issue. The paper presents the results of an Ignition Delay Time (IDT) study of a model fuel based on linear-chain hydrocarbons – n-pentane – with the addition of biofuels – methanol, ethanol, and isobutanol. The experiments were carried out with stoichiometric fuel-air mixtures with a content of biocomponents in the range from 10 to 85 % by weight using the shock tube setup. The studies were conducted at temperatures from 700 to 2100 K and pressures from 0.9 to 3.6 bar. A mathematical model has been constructed based on experimental data on the IDT of individual components and their mixtures.

添加含氧生物成分对碳氢化合物燃料点火影响的实验研究和数学建模


目前，全球商业航天、航空和其他行业的增长伴随着有害 CO2 排放对大气的负面影响的增加。然而，向生物燃料的过渡可能有助于解决这个问题。本文介绍了基于线性链碳氢化合物 - 正戊烷 - 添加生物燃料 - 甲醇、乙醇和异丁醇的模型燃料的点火延迟时间 （IDT） 研究的结果。使用激波管装置，使用生物成分含量为 10% 至 85%（重量）的化学计量燃料-空气混合物进行实验。这些研究是在 700 至 2100 K 的温度和 0.9 至 3.6 bar 的压力下进行的。基于单个组分及其混合物的 IDT 的实验数据构建了一个数学模型。
