A study on the impact of tunnel cross-sectional shape on the accidental dispersion and explosion characteristics of hydrogen

Key Points

• Accidental dispersion characteristics of hydrogen vary significantly with changes in tunnel shape.
• Key evidence shows that specific geometric configurations can increase explosion risk in confined spaces.
• The analysis used computational simulations to assess different tunnel cross-sectional shapes and their impacts.
• Improving tunnel design may enhance safety and reduce the likelihood of explosive incidents.
