摘要:
为了输氢管道的安全建设与运营,基于计算流体力学FLACS软件,模拟了埋地输氢管道在半受限空间内的泄漏爆炸事故后果,探讨了泄漏孔径、泄漏时长、输氢压力和环境风速对爆炸事故后果的影响规律,并得出相应的危险区域。结果表明:泄漏孔径、输氢压力和最大爆炸超压均与危险区域呈正相关关系,泄漏时长对事故后果几乎无影响;随着输氢压力的增大,危险区域受建筑物和风速的影响更为明显,在建筑物附近形成了狭长的危险区域带;最大爆炸超压和危险区域随环境风速的增大均呈现出先增大后减小的趋势。
Abstract:
For the safe construction and operation of hydrogen pipelines,based on the computational fluid dynamics (CFD) software FLACS,the leakage and explosion accident consequence of buried hydrogen pipeline in the semiconfined space was studied.The influence of leakage hole diameter,leakage duration,hydrogen transport pressure and ambient wind speed on the explosion accident consequence were studied,and the corresponding hazardous areas were proposed.The results showed that the leakage hole diameter and hydrogen transport pressure were positively correlated with the maximum explosion overpressure and hazardous areas,while the leakage duration had little effect on the accident consequence.As the hydrogen transport pressure increased,the hazardous area was more affected by the buildings and wind speed,and the narrow and long hazardous area zone formed near the buildings.Both the maximum explosion overpressure and the hazardous areas increased first and then decreased with the increase of ambient wind speed.
