    Abstract
  • 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.
