本文通过活化能渐近分析方法研究了非绝热正向阴燃波的两种典型结构,即反应滞后结构和反应前导结构,比较了当来流空气流量发生变化时两种结构的主要特征参数的变化规律。研究结果表明,相比较于绝热情况,当考虑阴燃向外界的对流热损失效应时,两种正向阴燃结构随来流空气流量变化时的一维响应均表现为两个解分支,相应地存在一个熄灭极限,对应最小的来流空气流量。 In this paper, two kinds of typical structures of non-adiabatic forward smoldering wave are studied by the method of activation energy asymptotic analysis, namely the reaction lag structure and the reaction leading structure. The main characteristic parameters of the two structures are compared when the incoming air flow changes The law of change. The results show that compared with the adiabatic case, considering the heat loss effect of smoldering to the outside, the one-dimensional responses of the two smoldering structures with the change of the air flow of the incoming air flow show two solution branches. Correspondingly, There is an extinction limit corresponding to the minimum incoming air flow.
