Abstract

“Physical detonation” is a phenomenon in which detonation is induced by not chemical, but physical, energy concentrated in internal degrees of freedom (in the present case, in vibrational degrees of freedom of hydrogen molecules). The possibility of emergence of such a phenomenon in hydrogen preliminarily excited to a certain temperature in a shock tube is investigated by the Monte Carlo method of nonstationary statistical simulation. The threshold value of such temperature, above which physical detonation is observed in the numerical experiment, is determined.

激波管中初步振动激发的氢流的“物理爆轰”极限

摘要

“物理爆轰”是这样一种现象，其中，爆炸不是由化学能量而是由物理能量引发的，而能量集中在内部自由度（在当前情况下是氢分子的振动自由度）中。通过非平稳统计模拟的蒙特卡罗方法研究了在激波管中预先激发到一定温度的氢中出现这种现象的可能性。确定该温度的阈值，在该阈值之上在数值实验中观察到物理爆震。
