| 摘 要： | 分析了蒸气云爆炸的发生条件、爆炸机理,介绍了蒸气云爆炸后果预测的Baker-Strehlow模型,阐述了Baker-Strehlow模型的基本原理,给出了无量纲距离和无量纲侧向峰值超压的关系,以及火焰传播速度选取的原则。对于约束很小的氢气-空气形成的气云的爆炸,将Baker-Strehlow模型的计算结果与实验结果进行了对比。此外对某区域的丙烷蒸气云的爆炸后果进行了预测,给出了伤害范围。

| Abstract: | Analyzed the occurring condition,the blast mechanism of VCE.Introduced Baker-Strehlow model,described the basal principle of Baker-Strehlow model.Given the relationship of dimensionless overpressure to combustion energy scaled distance and the principle of how to select flame speed.For VCE of hydrogen-air,we compared the result of Baker-Strehlow model and experiment.Predicted the consequence of a VCE by using this model,find the injure distance. |
