Abstract: The laminar flame speed of SiH4-N2O-Ar and SiH4-H2-N2O-Ar mixtures were measured for the first time using the spherically expanding flame technique. A detailed reaction model has been developed and demonstrates overall quantitative agreement with the experimental data. In addition, the c…

燃烧反应动力学模型对于理解燃烧过程、燃烧数值仿真、发动机及燃料设计等至关重要。然而，现如今的很多燃烧反应动力学模型的预测存在很大的不确定性，因此，燃烧反应动力学模型的分析和优化方法被广泛应用于量化并降低模型预测的不确定性。此前，常用的全局分析方法在燃烧领域的应用受到了计算成本的严重制约，只能应用于…

Abstract:A chemically consistent rate constant for the reaction between nitrogen dioxide and the oxygen atom has been obtained by combining low-temperature experimental data from the literature and new high-temperature quantum chemical calculations. The effect of the inclusion of the new rate cons…

Abstract:Direct detonation initiation by a point energy source in a rich H2–NO2/N2O4–Ar mix- ture has been investigated using high-resolution one-dimensional numerical simulations performed with detailed chemistry. In particular, the effect of the 2-step energy release profile on the critical in…
