正向阴燃波的结构和稳定性

本文通过数值计算方法系统研究了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。在此基础上,通过数值方法分析了这两种结构的线性稳定性。结果表明,在绝热条件下,对于文中所选参数取值,两种结构的正向阴燃波都是线性稳定的。

The Structure and Stability of Forward Smolder Waves

Two characteristic structures of forward smolder waves,namely reaction trailing structure and reaction leading structure,are investigated systematically using numerical approaches.A comparison is made of the responses of the characteristic quantities of the two structures with respect to the incoming air flow rate.On this basis,a linear stability analysis is carried out for the two structures,also using numerical methods.The stability analysis results show that,under adiabatic conditions,both the two struct...
