【摘要】 随液氢的广泛使用,液氢生产和使用过程的安全性将受到越来越多的重视。讨论了液氢泄漏后发生气化和在地表扩散特点。在此基础上,分析了液氢泄漏后可能发生的物理爆炸(如沸腾液体膨胀蒸气爆炸(BLEVE) 爆炸和急剧相变(RPT)爆炸)以及化学爆炸(如爆燃、高速爆燃、爆轰和气云爆炸)的特点。这些分析研究对液氢的安全使用,具有重要的参考价值。更多还原

【Abstract】 The safety of liquid hydrogen is being considered more and more with its increasing use. The liquid hydrogen vaporization and pool spreading behaviors were discussed in this paper. Based on the discussions, the characteristics of possible physical and chemical explosions were analyzed. The most common physical explosions are boiling liquid expanding vapour explosion (BLEVE) and rapid phase transition (RPT) explosion. Chemical explosion is consisting of deflagration, fast deflagration, detonation, gas cloud et al. These researches can provide technical support for the safe use of liquid hydrogen.更多还原
