温度具有空间分布的系统的热爆炸和起爆延滞期——Ⅱ.反应物消耗的影响

THERMAL EXPLOSION AND TIMES-TO-IGNITION IN SYSTEMS WITH DISTRIBUTED TEMPERATURES Ⅱ THE INFLUENCE OF REACTANT CONSUMPTION

本文在文献[1]的基础上,研究反应物消耗对临界性和起爆延滞期的影响。结果表明,此时需要对弗朗克-卡敏斯基参数δ的临界值进行修正,其数值为φ(g_w/B)^(2/3),系数φ和反应物形状等因素有关。文中给出了φ的数值,并进行了讨论。对于起爆延滞期,也进行了类似的修正和讨论。

This paper studies the influence of reactant consumption on criticality and on times-to-ignition, following the previous paper. It is shown that the influence of reactant consumption is to modify the critical value for Frank-Kamenetskii's parameter δ; the fractional increase is simply φ (g_w/B)^(2/3), where the coefficient φ depends on the geometry and other factors. Some typical values are given and discussed. Similar modification and discussion are also given for times-to-ignition.
