摘要
针对基于扩散点火理论的高压氢气泄漏自燃研究进展进行总结,对自燃机制、主要影响因素及变化规律进行阐述。介绍相关实验研究的发展变化过程,阐述该领域从定性研究到定量研究的过程中各阶段主要研究成果对于研究的推动作用,对于泄放压力、破膜条件、管道尺寸等主要影响因素的研究内容进行详细的对比分析。最后讨论现阶段存在的问题并展望了今后的发展趋势。
Based on diffusion ignition theory,the research progress and current status of high-pressure hydrogen spontaneous ignition were summarized,the postulate mechanisms of spontaneous ignition were explained and the main influencing factors of spontaneous ignition induced by shock were introduced.The development process of relevant experimental study and the promotion of the main research results from qualitative research to quantitative research in this field were introduced.The content of the research on the main influencing factors,such as venting pressure,membrane breaking conditions,and tube size was analyzed,and the problems existing at the current stage and the future development trends were discussed.
