AI Insight
This computational study investigated how different bifurcation angles in tunnel systems affect temperature distribution during fire events. The research used numerical simulations to model fire behavior at various junction angles where tunnels split, examining how the geometric configuration influences heat propagation and temperature patterns. The findings demonstrate that bifurcation angle significantly impacts thermal stratification and maximum temperature locations within the tunnel network.
Why it matters
Understanding temperature dynamics in bifurcated tunnels is critical for designing effective fire safety systems, evacuation protocols, and ventilation strategies in complex underground transportation infrastructure. These results can inform engineering standards for subway systems, highway tunnels, and underground facilities to improve fire safety and emergency response effectiveness.
