The skeleton of the new autoignition model is based on Shell model, which considers the effect of methane on autoignition of diesel.

由于着火过程持续时间较短，仅占湍流燃烧过程的一小部分，因此，在能够充分描述着火过程主要特征的情况下，着火模型应尽量简单，所以，虽然有文献提出了着火过程的详细化学动力学模型，实际上一般倾向用简化的化学动力学模型 [1]，这是Shell着火模型至今仍然得到广泛应用的原因。

A lifted turbulent H2/N2 jet flame in a hot and vitiated coflow is investigated numerically to explore the issues of autoignition as well as the flame lift-off.

采用数值方法研究了一个高温燃烧产物环境中的抬举湍流H2/N2射流火焰，对火焰的自然和抬举特性进行了研究。

The results show that the liftoff height of the CH4/Air jet flame decreases with the increase of the coflow temperature, and the change of the liftoff height versus the coflow temperature presents the twostages behavior, and the stabilization of lifted flame is dominated by the autoignition of premixed homogeneous mixture in lower coflow temperature range. The phenomena of rapid multipoint autoignition were observed in the experiment of diesel fuel spray issuing into the CATA, and a special lifted flame appeared with a triple flame.

结果表明：甲烷气体燃料火焰起升高度随协流温度的升高而降低，呈现出两阶段变化特点，低温段发生了明显的自燃现象，其火焰稳定由均质混合气自燃所主导；柴油液雾燃烧试验观察到了快速的多点自燃现象，形成了独特的起升火焰，有三重火焰的特征。
