本文通过求解物理空间中的层流扩散火焰面方程,建立火焰面数据库。相比于求解混合物分数空间的层流火焰面模型,该模型不仅简单,且易于耦合详细组分输运模型、Soret效应和气相辐射等影响因素。同时,求出的温度及组分浓度分布可以整理成各种不同参数的函数,提高了数据库使用的灵活性。本文对这种新的层流扩散火焰面模型进行详细的分析,并考察组分输运模型、Soret效应、气相辐射以及化学反应机理等因素对计算结果的影响。
In this paper, by solving the laminar flow in the physical space diffusion flame surface equation, the establishment of the flame surface database. Compared with solving the laminar flame model in fractional space of mixture, this model is not only simple but also easy to couple the influence factors such as detailed component transport model, Soret effect and gas phase radiation. At the same time, the calculated temperature and component concentration distribution can be arranged into various parameters of the function, improve the flexibility of the database. In this paper, the new laminar diffusion flame surface model is analyzed in detail, and the effects of component transport model, Soret effect, gas phase radiation and chemical reaction mechanism on the calculation results are investigated.
