摘　　要：LNG蒸气云爆炸事故后果严重,开展LNG蒸气云爆炸试验研究十分重要。通过对甲烷(LNG蒸气的主要成分)气云爆炸进行1∶100的缩尺试验研究,并与相同缩尺比例的甲烷爆炸数值模拟计算结果进行对比,验证了模拟结果和试验结果压力峰值的平均误差在30%左右,最大压力出现位置基本一致。可以认为模拟结果和试验结果有较好的一致性。因此在LNG储罐蒸气云爆炸研究过程中,可以考虑使用1∶1典型场景数值模拟对爆炸超压的发展情况进行分析。The consequences of LNG vapor cloud explosion are serious,so it is very important to carry out the test research on LNG vapor cloud explosion.Methane is the main component of LNG vapors.In this paper,a scale experiment of 1∶100 was carried out on methane gas cloud explosion test,and the results were compared with the numerical simulation of methane explosion of the same scale proportion.The test results showed that the average error of the pressure peak between the simulation results and the experimental results was about 30%,and the position of the maximum pressure was basically the same.The simulation results were in good agreement with the experimental results.Therefore,in the study process of LNG storage tank vapor cloud explosion,numerical simulation of a typical scenario of 1∶1 can be considered to analyze the development of explosion pressure.
