- 摘要:
- 针对含有43种组分201步基元反应的甲基肼/四氧化二氮反应机理，提出运用主成分联合多代通量方法（简称PP法）进行简化。该方法简化结果与国外文献以及详细机理在典型工况下着火延迟时间、平衡温度及主要平衡组分摩尔百分数计算结果均符合较好，为进行耦合化学反应的液体姿轨控火箭发动机燃烧CFD研究奠定基础。最后，通过甲基肼和四氧化二氮、CH4和O2 以及H2和O2三种推进剂组合化学反应机理简化结果对比，说明PP法相对于主成分分析法(PCA)和多代通量法(PFA)简化效果更好，可简化机理范围更广。
- Abstract:
- The method of principal component union multi-generation flux (PP method) is proposed in this paper to simplify reaction mechanism of monomethylhydrazine/nitrogen tetroxide with 43 species and 201 step elementary reactions. The simplified results of this method coincide well with the detailed mechanism calculated results (such as ignition delay time, equilibrium temperature, mole fraction of main equilibrium components) under typical conditions reported in foreign literature, which has laid the foundation for liquid attitude and orbit thruster combustion CFD study of the coupled chemical reaction. The comparison of the simplified result of the chemical reaction mechanism of three propellants (monomethylhydrazine/ nitrogen tetroxide, CH4 and O2, H2 and O2) indicates that the PP method is better than PCA and PFA. Its range to simplify mechanism is wider.
