摘要 剖析了沸腾液体扩展蒸气爆炸(BLEME)的发生、发展过程,阐述了其机理及相关条件,研究并提出了两种BLEVE火球热辐射模拟计算理论模型,即近地面和抬升火球模型,以及爆炸超压模型。与有关实验结果比较和与已有模型的对比计算表明了所建模型的有效性。 On the basis of accident-cause theory, mechanism of occurrence, progress and related conditions of boiling liquid expending vapor explosion(BLEVE) have been analyzed and studied. Two new models on heat radiation of fireball and overpressure of BLEVE have studied and put forward. Damage rules of heat radiation of fireball and overpressure of BLEVE have been used. Compared with experimental data and results from relevant models, the new models presented in the paper are proved to be effective and practical.
