2024年3月1日 · In this study, we employed numerical simulations and rigorous experimental validation to compare velocity and temperature field attributes between conventional tunnels and those augmented with fire compartments under diverse boundary conditions.
Overview of research on fire safety in underground road and …
2018年11月1日 · In case of a tunnel fire, fire ventilation systems are required to control smoke flows and create paths for evacuation and fire fighting. The tunnel fire ventilation systems mainly include longitudinal ventilation systems, smoke extraction ventilation systems, natural ventilation system and smoke control systems for cross passages and rescue ...
A Review of Tunnel Fire Evacuation Strategies and State-of-the …
2022年12月27日 · Once a fire occurs in the tunnel, the occupants face a dangerous and confined environment and need to evacuate before reaching untenable conditions. Failure in fire evacuation will cause severe injuries and casualties under high-temperature and toxic fire smoke, and many past fire accidents have taught us lessons.
The role of opened fire doors in enhanced heat exchange of long ...
2024年3月1日 · In tunnel fires, hot gas, called a ceiling jet, propagates beneath the ceiling from the fire source to the tunnel portals. The properties of the ceiling jet must be understood for conducting a ...
The paper presents a way of classification of fire resistance and smoke control doors placed in tunnels emergency exits on the basis of relevant tests in accordance with European Union...
The role of opened fire doors in enhanced heat exchange of long ...
Due to their distinctive structural attributes, fire compartments in utility tunnels result in regions of increased temperature concentration and thermal dissipation, notably influencing heat exchange phenomena.
The role of opened fire doors in enhanced heat exchange of long ...
2024年3月1日 · Driven by the necessity to understand the fire and smoke dispersion characteristics of electric bicycle (escooter) fires and their effects on residents’ safety in rural houses, this study was… With the rapid development of tunnel construction, more and more long tunnels are being designed and built.
