| 摘 要： | 建立了一个包含109组分和946个基元反应的煤油燃烧详细化学反应动力学模型,采用准稳态假设方法来对其进行简化,得到了包含22组分18步总包反应的简化反应模型.通过与典型实验结果和文献计算结果对比可以看出,简化模型具有较高的准确性,能够准确反映出RP-3航空煤油点火特性,能够用来对煤油燃烧问题进行准确的数值模拟.

| Abstract: | A detailed chemical kinetic mechanism containing 109 species and 946 elementary reactions for kerosene combustion was developed.With the use of quasi-stationary state approximation(QSSA) method,a reduced chemical kinetic mechanism including 22 species and 18 global reactions was obtained from the detailed kinetics.By comparing the reduced mechanisms with the typical experimental results and reference results,high precision of the reduced mechanisms is shown,which can be used to represent the ignition characteristic of RP-3 aviation kerosene fuel,and also simulate accurately the combustion of kerosene. |
