摘要(Abstract):

综述了高压氢气泄漏后相关燃爆事故及行为研究现状,总结了泄漏自燃、喷射火、气云爆炸等典型燃爆行为的研究现状、方法及结论,探明了典型氢泄漏后燃爆事故的关键控制参数,提出了现有高压氢气泄漏后燃爆风险实验及数值模拟研究存在的不足,并结合实际氢能场景,从实验尺度、初始条件、边界条件等方面对未来的研究方向进行了展望。
The research status of relevant combustion and explosion accidents and behaviors after high-pressure hydrogen leakage was investigated and introduced. This paper summarized the research status of relevant combustion and explosion accidents and behaviors after leakage, including research status, methods and conclusions of typical fire and explosion behaviors such as leakage spontaneous ignition, jet fire and gas cloud explosion, and explored the key control parameters of typical combustion and explosion accidents after hydrogen leakage. The shortcomings of the existing experimental and numerical simulation research on the risk of combustion and explosion after high-pressure hydrogen leakage were put forward. Combined with the actual hydrogen energy scenario, the future research direction was prospected from the aspects of experimental scale, initial conditions and boundary conditions.
