Despite the benefits of studying dynamical behavior of chemically reacting systems by bifurcation analysis, its utilization for large mechanisms is greatly limited by the lack of available software, and clear and published strategies for improving the technique. This paper reviews recent progress, and reports strategies we identified that greatly improve reliability and speed of computations. These are tested by combining two open-source software packages: AUTO-07p (bifurcation analysis) and Cantera (kinetics mechanism interpreter). Examples are shown for one-parameter and two-parameter bifurcation curves of methane partial oxidation. Cool and hot-flame regions and their dependence on secondary parameters can be identified and used to gain insight to previously unexplored operating regimes and potentially new reactor designs. Invariance in the bifurcation diagram provides evidence of successful mechanism reduction.

尽管通过分叉分析研究化学反应系统的动力学行为有很多好处，但由于缺少可用的软件以及改进该技术的明确且公开的策略，其在大型机理中的应用受到了极大的限制。本文回顾了最近的进展，并报告了我们确定的可大大提高计算的可靠性和速度的策略。通过组合两个开源软件包进行测试，这些软件包是：AUTO-07p（分叉分析）和Cantera（动力学机制解释器）。示出了甲烷部分氧化的一参数和二参数分叉曲线的例子。可以识别出冷热区域以及它们对次级参数的依赖性，并可以用来了解以前未探索的运行方式和潜在的新反应堆设计。
