High-pressured hydrogen's ejection caused by the structural failure of transport device could result in overpressure and mass fraction within the explosion limits. External flow field characters, hydrogen jet pressure, and mass fraction in the field were numerically simulated by using physical and calculation model in case of external flow field with or without obstacle. Hazardous area after hydrogen explosion and effect of obstacle on preventing hydrogen leakage and diffusion were obtained. The drawn conclusion could be the reference for prevention and treatment of hydrogen explosion accidents.

由于输运装置突然失效而引发的高压氢气喷射,能够在流场中造成超压和足以引发爆炸的扩散。运用数值计算方法,建立可用于计算的物理和数学模型对发生泄漏后有、无障碍物两种情况下的外部流场进行分析,可得到外部流场中的气体泄漏压力和浓度的分布等值线图。从计算结果可以得出氢气发生爆炸事故后的危险区域,障碍物对氢气的喷射泄漏以及爆炸所产生的影响,从而可为预防和处理氢气爆炸事故提供参考依据。

由于输运装置突然失效而引发的高压氢气喷射,能够在流场中造成超压和足以引发爆炸的扩散。运用数值计算方法,建立可用于计算的物理和数学模型对发生泄漏后有、无障碍物两种情况下的外部流场进行分析,可得到外部流场中的气体泄漏压力和浓度的分布等值线图。从计算结果可以得出氢气发生爆炸事故后的危险区域,障碍物对氢气的喷射泄漏以及爆炸所产生的影响,从而可为预防和处理氢气爆炸事故提供参考依据。

高压氢气  /  输运装置  /  物理爆炸

High-pressured hydrogen's ejection caused by the structural failure of transport device could result in overpressure and mass fraction within the explosion limits. External flow field characters, hydrogen jet pressure, and mass fraction in the field were numerically simulated by using physical and calculation model in case of external flow field with or without obstacle. Hazardous area after hydrogen explosion and effect of obstacle on preventing hydrogen leakage and diffusion were obtained. The drawn conclusion could be the reference for prevention and treatment of hydrogen explosion accidents.
