Abstract A reaction model is proposed for calculating the process of ignition of diborane mixtures with air. The model summarizes the previously developed kinetic models of oxidation of diborane, boron, as well as lower oxides and hydroxides of boron. A distinctive feature of the model is the use of physically grounded rate constants of the most important reaction channels, which were either computed or derived from available experimental data. The mechanism is tested against experimental data on the diborane ignition delay and flame velocity in diborane–oxygen and diborane–air mixtures. The results predicted by the proposed model are found to be in reasonable agreement with experimental data. The model can be used for engineering calculations and also for numerical simulations of diborane combustion in lean and stoichiometric mixtures with air.

乙硼烷混合物与空气点火的动力学机理

摘要 提出了一种计算乙硼烷与空气混合燃烧过程的反应模型。该模型总结了先前开发的乙硼烷、硼以及硼的低级氧化物和氢氧化物的氧化动力学模型。该模型的一个显着特点是使用了最重要的反应通道的物理接地速率常数，这些常数要么是计算出来的，要么是从可用的实验数据中得出的。该机制根据乙硼烷-氧气和乙硼烷-空气混合物中乙硼烷点火延迟和火焰速度的实验数据进行了测试。发现所提出的模型预测的结果与实验数据具有合理的一致性。该模型可用于工程计算，也可用于在稀薄和化学计量与空气的混合物中乙硼烷燃烧的数值模拟。
