约束爆炸会产生高温高压环境,该环境下,爆炸产物和空气中的氧气等成分极易发生化学反应。研究约束爆炸中涉及到的化学反应动力学过程,将动力学过程的具体参数耦合到约束爆炸中,可以获得约束爆炸后密封容器或者密闭爆室内更精确的总压力、静态压力和爆炸释放的总热量值,进而更准确地描述约束爆炸中的热应变、力学效应等重要物理现象,对于完善爆炸现象学研究具有重要的意义。通过总结国内外在这方面的研究工作,介绍了在约束爆炸研究中引入化学反应动力学过程的发展历史和最新进展,取得的研究成果,以及进行实验采用的技术方案和数值模拟方法。重点介绍了在化爆小当量约束爆炸的研究中,考虑化学反应动力学过程的实验研究方法和数值模拟方法,并分析指出了一些有待进一步研究解决的问题。
Research progress in chemical reaction kinetics applied in confined explosions
The confined explosions may cause a high-temperature and high-pressure environment. Under such environment, the explosive products and oxygen in the air easily have very active chemical reactions. The research on the chemical reaction kinetics of the confined explosions can get more accurate parameters, such as total pressure, static pressure and total energy, so the physical phenomena including the thermal strain and the mechanics effect can be described more accurately. This is important to consummate the explosion phenomenology. Summarizing the research work at home and abroad, a brief introduction to the developed history and latest investigation on the chemical reaction kinetics applied in the confined explosions was given, and the research results obtained as well as the experimental and the numerical simulation methods were also presented. The focus was on the experimental studies and the numerical simulations of the small equivalent confined explosions, and some further study and problems were pointed out.
