摘要
随着燃烧及爆炸相关内容的深入发展,一种新的爆炸模式进入了人们视野,即燃烧诱导快速相变(combustion-induced Rapid Phase Transition,cRPT)。对于cRPT的研究旨在发掘出除爆燃、爆轰之外的第三种爆炸模式,将为能量的获取提供更多有效途径。在总结cRPT的发展历程的基础上,综合详尽地叙述了cRPT的演化过程、突出特点、影响因素及应用价值,旨在为燃烧诱导快速相变现象更广泛的研究与应用提供参考。
With the development of combustion and explosion-related content,a new explosion mode has entered people’s vision,that is combustion-induced Rapid Phase Transition(cRPT).Combustion-induced rapid phase transition is a physical phase transition process of water during the chemical explosion process,and this phase transition process is continuously circulating.The research of cRPT aims to discover a third explosion mode other than deflagration and detonation,providing more effective ways to obtain energy.Based on summarizing the development process of cRPT,this paper comprehensively and detailedly describes the evolution process,prominent characteristics,influencing factors,and application value of cRPT.By comparison,it is concluded that high-frequency pressure oscillation is a necessary condition for the occurrence of cRPT,and the superadiabatic peak pressure can not be considered as the basis for judging whether cRPT can occur.In this paper,the phenomenon of pressure oscillation caused by cRPT and other explosion behaviors are compared,and the difference between them is mainly due to the high frequency of oscillation.The paper also summarizes previous theoretical formulas used to distinguish deflagration,cRPT and detonation,and clarifies the numerical criteria for dividing the three.Compared with deflagration and detonation,cRPT has its unique occurrence conditions.Temperature and water pressure,oxygen content,hydrogen or water content are the main influencing factors of cRPT.This paper believes that the in-depth study of cPRT provides theoretical guidance for effectively reducing the explosion hazard and rational utilization of resources,which is of great significance for enriching and improving the combustible gas explosion theory.Based on the analysis and summary of the article,further research on cRPT is necessary.It is reasonable to believe that cRPT will rapidly develop in the future and become a hot topic in the field of combustion.
